A) 50 %
B) 300 %
C) 100 %
D) 150 %
Correct Answer: C
Solution :
\[{{P}^{2}}=2mE\] \[\therefore \] \[P\propto \sqrt{E}\] \[\therefore \]\[\frac{{{P}_{1}}}{{{P}_{2}}}=\sqrt{\frac{{{E}_{1}}}{{{E}_{2}}}}=\frac{\sqrt{E}}{E+3E}=\frac{1}{2}\] \[{{P}_{2}}=2{{P}_{1}}\] Increase =\[\frac{{{P}_{2}}-{{P}_{1}}}{{{P}_{1}}}\times 100\] \[=\frac{2{{P}_{2}}-{{P}_{1}}}{{{P}_{1}}}\times 100=100%\]
