Common static electricity involves charges in the range between nanocoulombs and microcoulombs. How many electrons are needed to form a charge of Q1 = –6 nC?  how many electrons must be removed from a neutral object to leave a net charge of Q2 = 1.4 μC?

The two spherical shell has a charge of q1=0.30nC and q2 = 0.5nC. The radius of r1=7.5cm and r2 = 2.5cm. What is the new votage value in volts, after the charge transfer is completed between the two spheres?

Four identical metallic spheres with charges of +1.4 μC, +1.8 μC, -5.8 μC, and -5.2 μC are placed on a piece of paper. The paper is lifted on all corners so that the spheres come into contact with each other simultaneously. The paper is then flattened so that the metallic spheres become separated. (a) What is the resulting charge on each sphere? μC (b) How many excess or absent electrons (depending on the sign of your answer to part (a)) correspond to the resulting charge on each sphere? electrons are ---Select---

Two conducting spheres, A and B, have the same radius and sit on insulating stands. When they are touched together, 3.05×1013 electrons flow from sphere A to sphere B. If the total net charge on the spheres is +2.10 μC, what was the initial charge on sphere B?

The largest American Eagle gold has a mass of 28.4 g. The atomic number of gold (the numberof protons in the nucleus of an atom gold) is 79, and thus the number of electrons in a neutralgold atom is also 79. The atomic mass of gold is 197, which means that 1 mol of gold has massmAu = 197 g. How many electrons are contained in one pure gold coin? What is the totalnegative charged contained in the coin?

Four identical metallic spheres with charges of +9.0 µC, +2.6 µC, -3.4 µC, and -7.2 µC are placed on a piece of paper. The paper is lifted on all corners so that the spheres come into contact with each other simultaneously. The paper is then flattened so that the metallic spheres become separated. (a) What is the resulting charge on each sphere? µC (b) How many excess or absent electrons (depending on the sign of your answer to part (a)) correspond to the resulting charge on each sphere? electrons are ---Select--- Additional Materials Reading

Question 1. Two conductive spheres have the radius R1 = 0.2 m and R2 = 0.1 m. The spheres have the charge ql = 6 nC and q2 = -4 nC and are located at a distance from each other that is much larger than the radius of the spheres. A conductive wire is inserted between them so that charge can travel from one sphere to the other. The wire is then removed. How is the charge now distributed on the two spheres?

In the figure four particles form a square with edge length a = 2.24 × 10-2 m. The charges are 91-94 = 2.75 × 10-15 ℃ and 92 93 = 9. (a) What is q if the net electrostatic force on particle 1 is zero? (b) Is there any value of a that makes the net electrostatic force on each of the four particles zero? a) Number b) i 3 Units a a a 4 ·x
