A rocket with a lift-off mass `3.5xx10^4 kg` is blasted upwards with an initial acceleration of `10m//s^2`. Then the initial thrust of the blast is

A

`1.75xx10^(5) N`

B

`3.5xx10^(5)N`

C

`7xx10^(5) N`

D

`14xx10^(5) N`

Text Solution

Verified by Experts

The correct Answer is:
C
( c) Initial thrust must be
`m(g+a)=3.5xx10^(4)(10+10)`
`=7xx10^(5)N`
