• charging by convection

• charging by induction

• charging by conduction

• charging by friction

A solid conducting sphere is given a positive charge. How is the charge distributed in or on the sphere?

• It is concentrated at the center of the sphere.

• It is uniformly distributed throughout the sphere.

• Its density decreases radially outward from the center.

• It is distributed at the bottom of the sphere only.
