Question

The period of a body under SHM i.e. presented by T = $P^a{D}^b{S}^c$ ; where P is pressure, D is density and S is surface tension. The value of a, b and c are

• A.
• B. -1,-2,3
• C.
• D.

Answer 1

The correct option is A

By substituting the dimension of each quantity we get T = $\left[M{L}^{-1}{T}^{-2}{]}^a\right[L^{-3}M{]}^b[M{T}^{-2}{]}^c$
