Q1. A hollow cylinder of radius and height has a total charge uniformly distributed over its surface. The axis of the cylinder coincides with the z axis, and cylinder is centered at the origin.

To get the result into the final form, it is useful to remember that ln(x2) =2ln(x)

what is an electric potential (V) at the origin?

Q2. A thin, rigid, spherical shell with a mass of 6.00 kg and diameter of 0.400 m is filled with helium at 0 degrees Celsius and 1 atm pressure. It is then released from rest on the bottom of a pool of water that is 3.00 m deep.

A.) find out the upward acceleration of the shell.

B.) How long will it take for the top of the shell to reach the surface? Disregard frictional effects.
