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

Options

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

Answer

C

Explanation

Angular frequency `=2pif = [T^(-1)]`
a = 0, b = 0, c = - 1.
