A force vector applied on a mass is represented as `vec(F)=6 hat(i) - 8hat(j) + 10hat(k)` N and accelerates the mass at 5 `ms^(-2)` . The mass of the body is :

A

`2sqrt(2)`kg

B

40 kg

C

1.6 kg

D

`2sqrt(10)` kg

Text Solution

Verified by Experts

The correct Answer is:
A

`m=(|vec(F)|)/(|vec(A)|)=sqrt(36 + 64+100)/5=sqrt(2)/5`
`2sqrt(2)` kg
