21. The position of a particle in a specific rectilinear motion is given by x (t)-β (1-e p) where Vo& β are constants. Determine the dimensions of (VO β)

Answer»

since beta is on power with t so beta*(t) should be dimensionless therefore dimension of beta is 1/dim(t) = 1/sec = 1/T and since V•/beta should have dimension of L. so dimension of V = L*(1/sec) L/T
