Question

The three energy components in the potential energy formula for two charges in an external field represent:

Options

• the sum of individual external field interactions and mutual charge interaction

• kinetic and potential energy only

• only interactions with the external field

• only mutual interactions between charges

Answer 1

The complete formula U = q1V(r1) + q2V(r2) + \[\frac{q_1q_2}{4\pi\varepsilon_0 r_{12}}\] has three distinct physical components: the first term represents q1's interaction with the external field, the second term represents q2's interaction with the external field, and the third term represents the mutual Coulombic interaction between the two charges themselves.
