Question

0. The physical quantity which has dimensional formula MºLºT is
(a) Velocity
(b) time
(c) frequency (d) periodic time​

Answer 1

Answer:

The dimensional formula of a quantity, Q=[M

a

L

b

T

c

]

For option C : a=0 b=0 c=−1

The dimensions of that quantity Q=[T

−1

]

Angular frequency w=2πν

Hence the physical quantity is angular frequency as angular frequency has dimensions of [T

−1

].
