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

A

72 J

B

24 J

C

`-24 J`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
C
`W = W_(x) + W_(y)` , `W_(x) = vec F.x hat I, W_(y) = vec F. y hat j`.
