List of top Physics Questions on Electrostatic potential asked in BITSAT

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

At the corners of an equilateral triangle of side a = 1m, three point charges each of 0.1C are placed. If the system is supplied energy at the rate of 1kW, calculate the time required to move one of the mid-point of the line joining the other two.

Electric potential at any point is V = -5x + 3y + √(15)z. The magnitude of the electric field 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.

At the three vertices of an equilateral triangle of side \(a\), three point charges are placed (each of \(0.1\,\text{C}\)). If this system is supplied energy at the rate of \(1\,\text{kW}\), calculate the time required to move one of the charges to the mid-point of the line joining the other two.

Electric field in the region is given by \( \vec{E} = \left(\dfrac{M}{x^3}\right)\hat{i}\). The correct expression for the potential in the region is [assume potential at infinity is zero]:

A hollow metal sphere of radius 5 cm is charged such that the potential at its surface is 10 V. The potential at a distance of 2 cm from the centre of the sphere is:

In a region, the potential is represented by V(x,y,z)=6x-8xy-8y+6yz, where V is in volts and x,y,z are in metres. The electric force experienced by a charge of 2 coulomb situated at point (1,1,1) is:
