Question

Velocity of a particle is expressed by equation V=at2+ b/t sin cos. Find the dimension formula of a and 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]
