Let `vecF` be a force acting on a particle having positon vector `vecr. Let vecr` be the torque of this force about the origin then

A

`vecrxxvectau=0` and `vecFxxvectau=0`

B

`vecrxxvectau=0` and `vecFxxvectau!=0`

C

`vecrxxvectau!=0` and `vecFxxvectau=0`

D

`vecrxxvectau!=0` and `vecFxxvectau!=0`

Text Solution

Verified by Experts

`vectau=vecrxxvecF`, `vectau` is `bot^(ar)` to `vecr` and `vecF`
