PRACTICE / Electrostatic potential energy

A negative charge moves to higher potential

A charge of −2 μC moves from electric potential 10 V to 40 V.

Find its electric potential-energy change.

Organize the givens & assumptions
  • q = −2×10⁻⁶ C
  • Vi = 10 V
  • Vf = 40 V

Electrostatic potential difference is specified; charge stays fixed and does not disturb the source field.

  1. A−60 μJ-60\ \mathrm{\mu J}
  2. B60 μJ60\ \mathrm{\mu J}
  3. C−80 μJ-80\ \mathrm{\mu J}
  4. D−20 μJ-20\ \mathrm{\mu J}
