A) \[\frac{mu}{T}\]
B) \[\frac{2mu}{T}\]
C) \[\frac{4mu}{3T}\]
D) \[\frac{3mu}{4T}\]
Correct Answer: C
Solution :
Change in momentum = Impulse. = Area under force - time graph. \[\therefore \]mv = Area of trapezium \[=\frac{1}{2}\left( T+\frac{T}{2} \right){{F}_{0}}\]or \[mv=\frac{3T{{F}_{0}}}{4}\] or \[{{F}_{0}}=\frac{4mv}{3T}\] Hence, the correction option is (c).You need to login to perform this action.
