Dimensional formula for potential difference is

A point charge 2nC is located at origin. What is the potential at (1,0,0)?

If 100 J of work has to be done in moving an electric charge of 4C from a place where potential is -5 V to another place, where potential is V volt. The value of V is

A particle of charge q₁  = 3 μC  is located on x-axis at the point x₁  = 6 cm. A second  point charge q₂  = 2 μC  is placed on the x-axis at x₂  = -4 cm. The absolute electric potential at the origin is ​

Electric potential is

A long, hollow conducting cylinder is kept coaxially inside another long, hollow conducting cylinder of larger radius. Both the cylinders are initially electrically neutral.

Equal charges are given to two spheres of different radii. The potential will

Consider a solid cube made up of insulating material having a uniform volume charge density. Assuming the electrostatic potential to be zero at infinity, the ratio of the potential at a corner of the cube to that at the centre will be
