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

Options

A. spring constant, if a = 1, b = 1 and c = -2
B. surface tension, if a = 1, b = 1, and c = -2
C. force, if a = 1, b = 1 and c = 2
D. angular frequency, if a = 0, b = 0, and c = -1

Answer

D

Explanation

(a) `["ML T"^(-2)]="Force"implies"Wrong"`
(b) `["ML T"^(-2)]="Force"implies"Wrong"`
( c ) `["ML T"^(2)]="Not force"implies"Wrong"`
(d) `["T"^(-1)]="Angular frequency"`
`("rad s"^(-1))implies"Right"`.
