A force `vec F=(6 hati -8 hatj)N`, acts on a particle and displaces it over `4 m` along the X-axis and `6 m` along the Y-axis. The work done during the total displacement is

72 J

24 J

`-24 J`

Zero

Text Solution

Verified by Experts

The correct Answer is:

`(3)`

`W = W_(x) + W_(y), W_(x) = vec F. X hat i, W_(y) = vec F. Y hat j`
