A hydrogen atom contains one electron and one proton. (a) Find the electric force between the proton and the electron. (The distance between an electron and a proton in a hydrogen atom is 5.29 × 10-11 m. A proton’s positive charge has the same magnitude as the negative charge of an electron.) (b) What is the gravitational force between a proton and an electron? (c) If the electric force is stronger than the gravitational force, why don’t people accelerate toward charged combs, balloons, and other electrically charged objects?

- Sketch 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_forwardTwo particles with charges q1 and q2 are separated by a distance d, and each exerts an electric force on the other with magnitude FE. a. In terms of these quantities, what separation distance would cause the magnitude of the electric force to be halved? b. In terms of these quantities, what separation distance would cause the magnitude of the electric force to be doubled?arrow_forward(Figure 1) shows four electrical charges located at the corners of a rectangle. Like charges, you will recall, repel each other while opposite charges attract. Charge B exerts a repulsive force (directly away from B) on charge A of 3.0 N. Charge C exerts an attractive force (directly toward C) on charge A of 6.0 N. Finally, charge D exerts an attractive force of 2.0 N on charge A. 1. Assuming that forces are vectors, what is the magnitude of the net force F⃗ netF→net exerted on charge A? Express your answer in newtons. 2. What is the direction of the net force F⃗ netF→net exerted on charge A? Use the xy-plane with the origin at A and with x-axis directed to B. Express your answer in degrees measured clockwise from the negative y-axis.arrow_forward
- (Figure 1) shows five electric charges. Four charges with the magnitude of the charge 2.0 nCnC form a square with the size a� = 4.0 cmcm . Positive charge with the magnitude of q� = 2.0 nCnC is placed in the center of the square. What is the magnitude of the force on the 2.0 nCnC charge in the middle of the figure due to the four other charges?arrow_forwardA pair of positive and negative charges of 2.0*10^(-10) C are separated by 1.0*10^(-9) m. What is the electric filed magnitude 1.0*10(^-10) m from the positive charge and 2.0*10^(-10) from the negative charge? Note this point is on the line that passes througharrow_forwardTwo positive charges of magnitude 8.5 x 10-6 C each experience a repulsive electric force of magnitude 500 N. Calculate the distance between the two charges.(Give your answer in meters.)arrow_forward
- Two particles with the electric charges Q and -3 C are separated by a distance of 1.2m (a) If Q=4.5 C, what is the electric force between the two particles?arrow_forwardThe magnitude of the electrostatic force between two charged objects is 10N when they are separated by a distance of 10 m. If the same charges were separated by a distance of 5m, what will be the magnitude of the electrostatic force between them?arrow_forwardCharge 1 and charge 2 are separated by 34 cm and the magnitude of the electric force between them is 20N. The distance between them is changed, but the magnitudes of the charges do not change. The force between them now is 5 N. What is the distance between them now in cm?arrow_forward
- The electric force between two point charges, 6 cm apart, is 15 N. One of the charges has a value of 2 microcoulombs (2 x 10-6 C). What is the value of the other charge?arrow_forwardTwo charges q1=Q and q2 -3.3Q are separated by a distance d. The electric force between them is equal to F. If charge of q, is changed to 2.76Q and the separation between the charges is tripled, what would be the new electric force between them in terms of F. Round your answer to 1 decimal place. Moving to another question will save this response. « < Questionarrow_forwardAn electron experiences an electric force of 1.8×10^-11N at a distance of 5.0×10^-9 m from the nucleus of an ion. The electron is moved farther away, to a distance of 2.0×10^-8 m from the ion. What is the new electric force on the electron?arrow_forward
