Question

When a positive charge moves in the direction of the electric field, _____.

A. the field does negative work on it and the potential energy decreases

B. the field does zero work on it and the potential energy remains constant

C. the field does negative work on it and the potential energy increases

A. the field does negative work on it and the potential energy decreases

B. the field does zero work on it and the potential energy remains constant

C. the field does negative work on it and the potential energy increases

D. the field does positive work on it and the potential energy increases E. the field does positive work on it and the potential energy decreases

Explanation / Answer

(D). The field work positive work and potential energy decreases.

Since the direction of electric force and velocity is same so the work done by it will be positive.

Since potential energy is defined as work done by external force , and the work done by external force is negative here so potential energy decrease s.
