The energy stored in the capacitor is $'U'$. If an uncharged capacitor of same capacity is connected in parallel with it, then energy stored in each capacitor is
$\frac{U}{6}$
$\frac{U}{4}$
$\frac{U}{2}$
$U$
The amount of heat liberated in the circuit after closing the switch $S$ .
If the distance between two equal point charge is doubled then what would happen to the force between them ?
A wheel having mass $m$ has charges $+q $ and $-q$ on diametrically opposite points. It remains in equilibrium on a rough inclined plane in the presence of uniform vertical electric field $E =$
A square plate of side $'a'$ is placed in $xy$ plane having centre at origin if charge density of square plate is $\sigma = xy$ then. Total charge on the plate will be.
A negative charged particle is released from rest in a uniform electric field. The electric potential energy of charge
