The force is given in terms of time $t$ and displacement $x$ by the equation $F = A \cos B x + C \sin D t$

The dimensional formula of $\frac{A D}{B}$ is:

Answer:

Solution:

$[A] = [{MLT}^{- 2}]$

$[B] = [L^{- 1}]$

$[D] = [T^{- 1}]$

$[\frac{AD}{B}] = \frac{[{MLT}^{- 2}] [T^{- 1}]}{[L^{- 1}]}$

$[\frac{AD}{B}] = [{ML}^{2} T^{- 3}]$
