Question

An electron is brought from rest infinitely far away to rest at point P located at a distance of 0.041 m from a fixed charge q. That process required 101 eV of energy from an eternal agent to perform the necessary work.(a) What is the electric potential, in volts, at point P?

Answer 1

Answer:

The electric potential in volts is 1.618 x 10⁻¹⁷ V

Explanation:

The electric potential, in volts, at point P, can be calculated as follow;

Electric potential is the work done in moving a unit positive charge from infinity to a particular point in the electric field.

Thus, the work done in this process in moving the charge to point p is 101eV.

Convert this Volts = 101 × 1.602 x 10⁻¹⁹ V

                              = 1.618 x 10⁻¹⁷ V

Therefore, the electric potential in volts is 1.618 x 10⁻¹⁷ V
