-5.0\,\text{nC}

charge is carried sequentially from point A to point B to point C. The electric potentials at the three points are

V_A = 30\,\text{V}

V_B = -10\,\text{V}

, and

V_C = 60\,\text{V}

, respectively. What is the net change in the charge’s electric potential energy after the entire trip from A
