A body, constrained to move in the Y-direction is subjected to a force given by `vecF=(-2hati+15hatj+6hatk)N`. What is the work done by this force in moving the body a distance 10 m along the Y-axis

A

20J

B

150J

C

160J

D

190J

Text Solution

Verified by Experts

The correct Answer is:
B

Work done `(W)= vec(F).vec(S)`
`= (-2hat(i) + 15hat(j) + 6hat(k)). (10 hat(j))` = 150J
