If `alpha=F/v^(2) sin beta t`, find dimensions of `alpha` and `beta`. Here v=velocity, F= force and t= time.

Text Solution

Verified by Experts

Here `sin beta t and betat` must be dimensionless.
So `[betat] = 1 rArr [beta] [(1)/(t)] = [T^(-1)] , [alpha] = [(F)/(v^(2)) sin beta t] = [ (F)/(v^(2))] = [ (MLT^(-2))/(L^(2)T^(-2))] = [ML^(-1)]`
