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

A positively charged body $A$ has been brought near a neutral brass sphere $B$ mounted on a glass stand as shown in the figure. The potential of $B$ will be: 

The amount of work done by electric field in joules in carrying a charge $+q$ along the closed path PQRSP between the oppositely charged metal plates is  (where, $E$ is electric field between the plates) 

Figure shows a closed surface which intersects a conducting sphere. If a positive charge is placed at the point P, the flux of the electric field through the closed surface: 

An ellipsoidal cavity is carved within a perfect conductor. A positive charge $q$ is placed at the centre of the cavity. The points $A \text{and} B$ are on the cavity surface as shown in the figure. 

The figure shows the current $I$ in a single-loop circuit with a battery $B$ and resistance $R$ (and wires of negligible resistance). Then find the order of following at the point $a\mathit{,}\mathit{ }b$ and $c$.

(a) The magnitude of the current,

(b) The electric potential, and

(c) The electric potential energy of the charge carriers (electron), the greatest first.
