A machine gun fires bullets of 50gm at the speed of 1000m/sec. If an average force of 200N is exerted on the gun, the maximum number of bullets fired per minute is:

A

240

B

120

C

60

D

30

Text Solution

Verified by Experts

The correct Answer is:
A
`(200)/((50)/(1000)xx1000)=4` bullet/second
`therefore 240` bullet/min
