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

`3.5xx10^(5)N`

B

`7.0xx10^(5)N`

C

`14.0xx10^(5)N`

D

`1.75xx10^(5)N`

Text Solution

Verified by Experts

The correct Answer is:
A
Here, thrust force is responsible to accelerate the rocket, so inittal thrust of the blast.
`F=ma`
`F=3.5xx10^(4)xx10`
`=3.5xx10^(5)N`
