Question

Periodic time is depends on length and gravitational acceleration. Find dimensional formula of all the quantity. ​

Answer 1

Answer:rfe

Explanation:rfe

Answer 2

1. length of pendulum (l)- L^1
2. gravitational acceleration (g)- LT^-2
3. Time Period (T)- T^1

Explanation

after dividing the dimensions only T^-2 remains and its root is taken.

T=2π(√l/g)
