The torque of a force F = - 6 hat (i) ac...

The torque of a force `F = - 6 hat (i)` acting at a point `r = 4 hat(j)` about origin will be

A

`-24 hat(k)`

B

`24 hat(k)`

C

`24 hat(j)`

D

`24 hat(i)`

Text Solution

Verified by Experts

The correct Answer is:
B
Torque, `tau=r xx F`
`implies tau = 4hat(j)xx-6hat(i)=-(-24 hat(k))=24 hat(k)`
