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 `=2pixx`frequency
`=[T^(-1)]=[M^(0)L^(0)T^(-1)]`
`thereforea=0,b=0,c=-1`
