Three charges q, q and Q ($q=+20~\mu C$ and $Q=+10~\mu C$) are placed on the circumference of a circle of radius $10\sqrt3$ cm. If the distance between any two charges is same, then the total electrostatic potential energy of the system of the three charges is

Two points A and B are located at distances 4 cm and 5 cm respectively from a point charge $+20\mu C$. The work done in taking a charge of $+2\mu C$ from point A to point B is

The charge on a parallel plate capacitor is 200 μC and its capacitance is 4 μF. If the distance between the plates of the capacitor is 2 mm, then the electric force between the plates of the capacitor is

If a charge of 3 nC is placed at each vertex of a cube of side 3 m, then the electric potential at the centre of the cube is:
