The Correct Option is C

Solution and Explanation

Here : \infty , log(1+e) \log (1+e) P=13mnc2V P=\frac{1}{3}\frac{mn{{c}^{2}}}{V} P=13m2n(2c)2V P=\frac{1}{3}\frac{\frac{m}{2}n{{(2c)}^{2}}}{V} Now, PP=2 \frac{P}{P}=2 P:P=1:2 P:P=1:2 or =F.s=(2i^+4j^).(3j^+5k^) =\overrightarrow{F}.\overrightarrow{s}=(2\hat{i}+4\hat{j}).(3\hat{j}+5\hat{k})
