Accelerate NEET 2020: Electrostatics Class 5 (27.08.2019)

A hollow metal sphere of radius 5 cm is charged such that the potential on its surface is 10 volts. The potential at the centre of the sphere is

If the potential function is given by V = 4x + 3y, then the magnitude of electric field intensity at the point (2, 1) will be

The electric potential V at any point x, y, z (all in metres) in space is given by V = 4x²volt. The electric field at the point (1m, 0, 2m) in volt/metre is

Potential at a point x-distance from the centre inside the conducting sphere of radius R and charged with charge Q is

q, 2q, 3q and 4q charges are placed at the four corners A, B, C and D of a square. The field at the centre O of the square has the direction along.
