Question

The velocity v of a particle at time t is given by v=at+b/t+c

Answer 1

Answer:

Explanation:

According to the principle of dimensional homogenity

Dimension of v = dimension of at  =  dimension of  $\frac{b}{t+c}$

Dimension of a = [v] / [t]   =$\frac{LT^-2}{T}$=[LT^-2]

Dimension of b=[v][t]=[LT^-1T] =[L]

Dimension of c=[t]=[T]
