A) \[\frac{mv}{n}\]
B) \[\frac{mv}{ng}\]
C) \[\frac{{{m}^{2}}{{v}^{2}}}{{{n}^{2}}}\]
D) nmv
Correct Answer: D
Solution :
As, the change of momentum for a bullet is mv Average time for the firing of one bullet \[=\frac{1}{n}\]second Now, average force \[=\frac{\Delta p}{\Delta t}\] \[=\frac{mv}{1/n}=mnv\]You need to login to perform this action.
