To move a charge of 0.01 C from point A to point B against an existing electric field, 12 J of work must be performed. What is the potential difference V_B - V_A ?

Options

A1200 V
B120 V
C-1200 V
D0.12 V

Correct answer

A. 1200 V

Step-by-step solution

The work done by an external agent in moving a charge q from point A to point B against an electric field is given by W = q(V_B - V_A) . Substituting the given values: 12 = 0.01(V_B - V_A) V_B - V_A = 12 0.01 = 1200 V
