Force F = P ( Ax )+ Q Sin ( Bt ) where x and t are displacement and time respectively. Which one of the following physical quantity has the dimensions of [ B A ] ?
Options
- Avelocity gradient
- Bvelocity
- Cangular velocity
- Dangular momentum
Correct answer
B. velocity
Step-by-step solution
F=P (A x)+ (B t) Bt = no unit Ax = no unit [B]= [T⁻¹ ][A]= [L⁻¹ ] [ B A ]= [L T⁻¹ ] velocity dimensions.
