A body, under the action of a force vec(...

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

200 kg

B

20 kg

C

`10sqrt(2)kg`

D

`6 sqrt(2) kg`

Text Solution

Verified by Experts

The correct Answer is:
C
`m=sqrt(6^(2) + (-8)^(2) + 10^(2))`
`m=sqrt(36+64+100)=10sqrt(2)`
