W-Q-x394-V-Q-Vq-x2212-Vp-W-100-xD7-x2212-1-6-xD7-10-x2212-19-xD7-x2212-14-2-24-xD7-10-x2212-16 J

Two points $P$ and $Q$ are maintained at the potentials of $10 V$ and $- 4 V$ , respectively. The work done in moving 100 electrons from $P$ to $Q$ is :
$2.24 \times 10^{- 16} J$
$- 2.24 \times 10^{- 16} J$
$9.60 \times 10^{- 17} J$
$- 9.60 \times 10^{- 17} J$

$W = Q Δ V = Q (V_{q} - V_{p})$
$W = 100 \times (- 1.6 \times 10^{- 19}) \times (- 14)$
$= 2.24 \times 10^{- 16}$ J

Two points P and Q are maintained at the potentials of 10 V and −4V, respectively. The work done in moving 100 electrons from P to Q is :2.24×10−16 J−2.24×10−16 J9.60×10−17 J−9.60×10−17 J

W=QΔV=Q(Vq−Vp)W=100×(−1.6×10−19)×(−14)=2.24×10−16 J
