A hollow conducting sphere is placed in an electric field produced by a point charge placed at $P$ as shown in figure. Let $V_A, V_B, V_C$ be the potentials at points $A, B$ and $C$ respectively. Then
$V_C\,\, > \,\,V_B$
$V_B\,\, > \,\,V_C$
$V_A\,\, > \,\,V_B$
$V_A\,\, = \,\,V_C$
If $\vec E = \frac{{{E_0}x}}{a}\hat i\,\left( {x - mt} \right)$ then flux through the shaded area of a cube is
A point charge $q$ is placed at a distance $\frac{a}{2}$ directly above the centre of a square of side $a$ . The electric flux through the square is
If an insulated non-conducting sphere of radius $R$ has charge density $\rho .$ The electric field at a distance $r$ from the centre of sphere $(r < R)$ will be
The equivalent capacitance of the system of capacitors between $A$ and $B$ as shown in the figure
The force on a charge situated on the axis of a dipole is $F$. If the charge is shifted to double the distance, the new force will be
