A body, under the action of a force `vec(F)=6hati -8hatj+10hatk` , acquires an acceleration of `1ms^(-2)` . The mass of this body must be.

A

`10 sqrt(2)kg`

B

`2sqrt(10)kg`

C

`10kg`

D

`20kg`

Text Solution

Verified by Experts

The correct Answer is:

A

`m=(|vecF|)/(a)=sqrt(200)/(1)=10sqrt(2)` kg
