A body under the action of a force `vec(F)=6hat(i)-8hat(j)N` acquires an acceleration of `5ms^(-2)` . The mass of the body is

A

2kg

B

5kg

C

4kg

D

6kg

Text Solution

Verified by Experts

The correct Answer is:
A

`"Given": overset(-)(F)=6 hati-hat8i N, a=5ms^(-2)`
`therefore F=sqrt((6)^(2)+(-8))=10N`
Mass of the body is, `m=(F)/(a)=(10N)/(5ms^(2))=2kg`
