The work done by a force on a body moving from (1,4) m to (3,8) m is 44 J. The force can be :

A

`8 hat i+6hatj N`

B

`8 hati-8 hatjN`

C

`6 hati-8 hatj N`

D

`6 hati+8 hatj N`

Text Solution

Verified by Experts

The correct Answer is:
D
`W=vec(F).vec(S)`
`44=vec(F)(2hati+4hatj)`
by hit and trial `(6hati+8hatj).(2hati+4hatj)=44 J`
