Asked in MDCAT Test Series — Electrostatics, Work and Energy

The electric potential at infinite distance is:

Correct answer: B. Zero

  • A. Infinity
  • B. Zero
  • C. Negative
  • D. Positive

Explanation

Option B is correct since the electric potential at infinite distance is zero.Electric potential is the amount of electric potential energy per unit charge at a given point in space. It is measured in volts (V). At infinite distance from a charge or collection of charges, the electric field strength becomes negligible, and the electric potential approaches zero.

About Electric Potential

Electric potential is the work done per unit positive charge in bringing it from infinity to a point, while potential difference compares energy change between two points. Work includes potential due to point charges, superposition of scalar potentials, equipotential surfaces, and the relation between electric field and potential.
