Question

A student measures the electric flux through a closed spherical surface of

volume V to be X. She then removes the charge from inside the spherical

surface and places it in a closed cylindrical surface of volume V/2. She then

claims that the flux through the cylindrical surface is 2X. Is the student right or

wrong ? Give reasons to your answers
b) A uniform charged conducting sphere of 1.2m diameter has a surface charge density

of 8.1µ c/m2 . Find;
i) The net charge on the sphere.

ii) What is the total electric flux leaving the surface of the sphere?

Describe the changes to the magnitude and direction of the force on one of the

charges in an electric dipole when the distance between the charges increase.
