For a body, angular velocity (vecomega)=...

For a body, angular velocity `(vecomega)=hati-2hatj+3hatk` and radius vector `(vecr)=hati+hatj+hatk`, then its velocity:

Text Solution

Verified by Experts

The correct Answer is:
C
By Newton's formula
`eta=("dimensions of force")/("dimensions of area"xx "dimensions of velocity gradient")`
`=([MLT^(-2)])/([L^(2)][T^(-1)])=[ML^(-1)T^(-1)]`
