A cylinder on whose surfaces there is a vertical electric field of varying magnitude as shown. The electric field is uniform on the top surface as well as on the bottom surface therefore, this cylinder encloses

A metallic solid sphere is placed in a uniform electric field. The lines of force follow the path(s) shown in figure as :

Figure shows a thick metallic sphere. If it is given a charge $+Q$, then electric field will be present in the region.

Two small conductors $A\text{ and }B$ are given charges $q_1$ and $q_2$, respectively. Now they are placed inside a hollow metallic conductor ($C$) carrying a charge $Q$Q. If all the three conductors $A, B\text{ and }C$ are connected by conducting wires as shown, the charges on $A, B\text{ and }C$ will be respectively
