List of top Physics Questions on Electrostatic potential asked in COMEDK UGET

A uniform electric field of $5 \times 10^3\text{ N C}^{-1}$ is maintained in the positive Y-direction. Now a point charge of $2 \times 10^{-4}\text{ C}$ at rest is released from the origin. The kinetic energy attained by the charge when it is at a distance of $5\text{ m}$ from the origin is:

Three charges, \( Q \), \( -q \) and \( 2q \) are placed at the vertices of a right-angled isosceles triangle. What is the value of \( q \) for the net electrostatic energy of the configuration to be zero?

When a metallic spherical shell of radius 20 cm is charged, the potential on its surface is found to be 5 V. The potential at a point 10 cm from the centre of the spherical shell is:

Three point charges \( -1C, +1C, +1C \) are placed at points \( A, B, C \) respectively of a triangle \( ABC \). What is the total potential energy of the system? [given \( AB = AC = 6 \, \text{cm} \) and \( BC = 3 \, \text{cm} \)]
