Forces in an atom. The particles in the nucleus of an atom are approximately 10−16 m apart, while the electrons in an atom are about 10−10 m from the nucleus, (a) Calculate the electrical repulsion between two protons in a nucleus if they are 1.00 × 10−15 m apart. If you were holding these protons, do you think you could feel the effect of this force? How many pounds would the force be? (b) Calculate the electrical attraction that a proton in a nucleus exerts on an orbiting electron if the two particles are 1.00 × 10−10 m apart. If you were holding the electron, do you think you could feel the effect of this force?

Introduction to Electrodynamics
- Each of the following statements is related to conductors in electrostatic equilibrium. Choose the words that make each statement correct. (i) The net charge is always zero [(a) inside; (b) on] the surface of an isolated conductor. (ii) The electric field is always zero [(c) inside; (d) just outside] a perfect conductor. (iii) The charge density on the surface of an isolated, charged conductor is highest where the surface is [(e) sharpest; (f) smoothest].arrow_forwardCommon static electricity involves charges ranging from nanocoulombs to microcoulombs. (a) How many electrons are needed to form a charge of 2.00 nC (b) How many electrons must be removed from a neutral object to leave a net charge of 0.500 C ?arrow_forwardIs it possible for a conducting sphere of radius 0.10 m to hold a charge of 4.0 C in air? The minimum field required to break down air and turn it into a conductor is 3.0 106 N/C.arrow_forward
- In a certain region of space, the electric field is E = 6.00 103 x2i, where E is in newtons per coulomb and x is in meters. Electric charges in this region are at rest and remain at rest. (a) Find the volume density of electric charge at x = 0.300 m. Suggestion: Apply Gausss law to a box between x = 0.300 m and x = 0.300 m + dx. (b) Could this region of space be inside a conductor?arrow_forwardTwo 25.0-g copper spheres are placed 75.0 cm apart. Each copper atom has 29 electrons, and the molar mass of copper is 63.5463 g/mol. What fraction of the electrons from the first sphere must be transferred to the second sphere for the net electrostatic force between the spheres to equal 100 kN?arrow_forwardSketch the electric field lines in the vicinity of two opposite charges, where the negative charge is three times greater in magnitude than the positive. (See Figure 1S.47 for a similar situation).arrow_forward
- Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. Silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. Imagine adding electrons to the pin until the negative charge has the very large value 1.00 mC. How many electrons are added for every 109 electrons already present?arrow_forwardRecall Coulomb's Law, which says that |?|=?|?1?2|?2|F|=k|Q1Q2|r2 , where |F| is the size of the electrical force, the Qi are charges, r is the distance between the charges, and k is a constant. The units of k can be written as Ma Lb Tc Qd. What is b?arrow_forwardFlying insects such as bees may accumulate a small positive electric charge as they fly. In one experiment, the mean electric charge of 50 bees was measured to be ++(30 ±± 5) pCpC per bee. Researchers also observed the electrical properties of a plant consisting of a flower atop a long stem. The charge on the stem was measured as a positively charged bee approached, landed, and flew away. Plants are normally electrically neutral, so the measured net electric charge on the stem was zero when the bee was very far away. As the bee approached the flower, a small net positive charge was detected in the stem, even before the bee landed. Once the bee landed, the whole plant became positively charged, and this positive charge remained on the plant after the bee flew away. By creating artificial flowers with various charge values, experimenters found that bees can distinguish between charged and uncharged flowers and may use the positive electric charge left by a previous bee as a cue…arrow_forward
- In frictional electrification, when two different, electrically neutral objects are rubbed together, electrons are transferred from one object to another, making them electrically charged. Consider that in an experiment a group rubbed a glass rod on a piece of silk, with a quantity of electrons being transferred from the glass to the piece of silk. The glass became positively charged, with an electrical charge of 1.39∙10-17 C. Determine the number n of electrons that were transferred from the glass rod to the silk. Round the answer to a positive integer. Consider the elementary charge to be e = 1.602∙10^-19C.arrow_forwardA charged ion with charge of +2.65 x 10-19 C and a mass of 3.15 x 10-27 kg is held halfway between two oppositely charged plates with voltage of 3.06 x 104 V.
