A) 550 N
B) 50 N
C) 250 N
D) 250 dyne
Correct Answer: B
Solution :
u = velocity of bullet \[\frac{dm}{dt}=\]Mass thrown per second by the machine gun = Mass of bullet × Number of bullet fired per second \[=10\ g\times 10\ bullet/\sec \]\[=100\ g/\sec \ =\ 0.1\ kg/\sec \] \[\therefore \] Thrust \[=\frac{udm}{dt}=500\times 0.1=50\ N\]You need to login to perform this action.
