Question

The velocity v of a particle at a time t is v= (A/ t 2 ) + Bt. Write the dimensional formula of A/B.​

Answer 1

Answer:

According to the principle of dimensional homogenity

Dimension of v = dimension of at = dimension of

t+c

b

Dimension of a =

[t]

[v]

=

T

LT

−2

=[LT

−2

]

Dimension of b = [v][t]=[LT

−1

T]=[L]

Dimension of c = [t]=[T]
