A) half
B) remain unchanged
C) be doubled
D) increase \[\sqrt{2}\]times
Correct Answer: A
Solution :
Kinetic energy of particle, \[K=\frac{p_{1}^{2}}{2m}\] \[p_{1}^{2}=2mK\] When kinetic energy\[=2K\] \[p_{2}^{2}=2m\times 2K\] \[\Rightarrow \] \[p_{2}^{2}=2p_{1}^{2}\]or\[{{p}_{2}}=\sqrt{2}{{p}_{1}}\]You need to login to perform this action.
