(b) $200$

(d) $50$

Show Answer

Answer:

Correct Answer: 25. (c)

Solution:

$p = \sqrt{2 m E}$ and $p^{'} = \sqrt{2 m E^{'}}$

$\frac{p^{'}}{p} = \sqrt{\frac{2 m \times 4 E}{2 m E}} = 2$

$\begin{aligned} \frac{p^{'}}{p} - 1 = 2 - 1 [on substrating 1 in both sides.] \\ \frac{p^{'} - p}{p} \times 100 = (2 - 1) \times 100 = 100 \end{aligned}$
