A) \[P\]
B) \[\sqrt{3p}\]
C) \[p\sqrt{5}\]
D) zero
Correct Answer: C
Solution :
Momentum of the third part will be equal to the resultant of momenta of two parts \[{{p}_{3}}=\sqrt{p_{1}^{2}+p_{2}^{2}}\] \[{{p}_{3}}=\sqrt{{{(-2p)}^{2}}+{{p}^{2}}}\] \[{{p}_{3}}=p\sqrt{5}\]You need to login to perform this action.
