Two metal spheres of identical mass m = 4.60 g are suspended by light strings 0.500 m in length. The left-hand sphere carries a charge of 0.765 µC, and the right-hand sphere carries a charge of 1.47 μC. What is the equilibrium separation between the centers of the two spheres? 0.6078 x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four- digit accuracy to minimize roundoff error. m

A stationary block has a charge of +6.0 x 10^-4 C. A 0.80-kg cart with a charge of +4.0 x 10^ -4 C is initially at rest and separated by 4.0 m from the block. Calculate the cart’s speed after it is released and moves along a frictionless surface to a distance of 10.0 m from the block.

A factory is spray-painting large sheets of metal electrostatically.  The sheets have dimensions of 2.4 m by 2.4 m and are charged with 0.82 mC.  A 10 kg drum of paint is charged with -89 μCμC, and the spray nozzle produces uniform droplets of 2.4 g.  Assume that all charge is distributed uniformly on the sheet and in the paint and no charge is lost during the spraying process.  Determine the magnitude of acceleration the paint droplets feel due to the metal sheet.   Give your answer in units of ms2ms2.

A 8-g charged plastic sphere charged to 75 µC is on top of a plastic spring with spring constant k = 400 N/m, which has a relaxed length of 10 cm. You then place another charged object 1 cm above (not touching) the sphere. Now, the spring is 9.5 cm long. Find the charge on the new second object.
