Q: A positive charge is moved from a low potential point A to a high potential point B. Then the electric potential energy:
(a) Increases
(b) decreases
(c) will remain the same
(d) nothing definite can be predicted
Ans: (a)
Sol: $\large \Delta U = q (V_B – V_A ) $
$\large \Delta U = q \Delta V $
As ΔV increases , so ΔU increases .
