A rocket is going upward with acceleration motion. A man string in it feels his weight increased 5 time his own weight. If the mass of the rocket including that of the man is `1.0xx10^(4)kg` , how much force is being applied by rocket engine? `(Take g=10ms^(-2))` .

A

`5xx10^(4)N`

B

`5xx10^(5)N`

C

`5xx10^(8)N`

D

`2xx10^(4)N`

Text Solution

Verified by Experts

The correct Answer is:
B
As the weight of man increased by 5 times, so acceleration of the rockets, `a=5g=5 xx 10=50ms^(-2)`
Force applied by roccket engine is
`F=ma=1.0xx10^(4)xx50=5xx10^(5)N`
