Question

check whether following equation is correct or not T=2π√l/g​

Answer 1

Answer:

The given statement is correct.

Explanation:

Here

T is a periodic time.

l = length in meters

g = acceleration = length / time^2

So

I /g = (length/length) * time^2

√(l/g) = time

So the dimensions match.

Answer 2

Answer:

2π is constant so no dimensions

units of g are metre/sec^2 so it is L/T^2

√L/L/T^2=T units of time is seconds and its dimensional formula is T so its proved...
