Question

The velocity v of a particle at time t is given by
b
V = at +
where a, b and c are constants.
ttc
The dimensions of a, b and c are respectively.
R. T and LT
L, LT and T
LT-2. L and T
LT?. LT and L​

Answer 1

Answer:

According to the principle of dimensional homogenity

Dimension of v = dimension of at  =  dimension of t+cb

Dimension of a =  [t][v]=TLT−2=[LT−2]

Dimension of b = [v][t]=[LT−1T]=[L] 

Dimension of c = [t]=[T]
