Problem

Calculate the minimum work that an external agent must do to move a

-2.0\,\mu\text{C}

point charge slowly from point A (electric potential

+12\,\text{V}

) to point B (electric potential

-3\,\text{V}

). Assume the charge’s speed is negligible throughout. a)

60\,\mu\text{J}

-30\,\mu\text{J}

30\,\mu\text{J}

15\,\mu\text{J}
