Question

The time period of a simple pendulum is given by T=1/2π √l/g where T is the time, 'l' is length and 'g' is acceleration due to gravity. Check whether the equation is dimensionally correct

Answer 1

Answer:

correct

Explanation

Time dimention is second

length have metre

n g have m/ s square

metre cancels metre and upon second square comes on numenater and comes out from under root .

hence second equals second
