The dimensional formula of physical quantity is `M^(a) L^(b) T^( c)` . Then that physical quantity is

A

surface tension if `a=1,b=1,c=-2`

B

force if `a=1,b=1,c=2`

C

angular frequency if `a=0,b=0,c=-1`

D

spring constant if `a=1,b=-1,c=-2.`

Text Solution

Verified by Experts

The correct Answer is:
C
Angular frequency `omega=(2pi)/(T)`
`:.` So dimensional formula of angular frequency is `M^(0)L^(0)T^(-1)`
So cannot choice is `(c )`.
