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