Question
Two points P and Q are maintained at the potential of 10V and -4V respectively. The work done in moving 100 electrons from P to Q is
-
9.60 × 10–17 J
-
9.60 × 10–17 J
-
– 2.24 × 10–16 J
-
2.24 × 10–16 J
Solution
D.
2.24 × 10–16 J
W = QdV = Q(Vq - VP)
= -100 × (1.6 × 10-19) × (– 4 – 10)
= + 100 × 1.6 × 10-19 × 14 = +2.24 10-16 J
