Question

The velocity v of a particle at time t is given by v= at2

+bt+c

Where a, b, c are constants. The dimension of a, b, c are​

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]
