Show that the expression of the time period T of a simple pendulum of length l given by `T = 2pi sqrt((l)/(g))` is dimensionally correct

Text Solution

Verified by Experts

`T=2pisqrt((l)/(g))`
Dimensionally `[T]=sqrt(([L])/([LT^(-2)]))=[T]`
As in the above equation, the dimensions of both sides are same. The given formula is dimensionally correct.
