Question

The length of two pendulums are 80cm and 20cm.calculate the ratio of their time periods.​

Answer 1

Answer:

Hi !!!

The longer the length of string, the farther the pendulum falls; and therefore, the longer the period.

Given,

L1 = 80 cm

L2 = 20 cm

T1/T2 = L1/L2

T1/T2 = 80/20

T1/T2 = 4/1

Thus,

T1:T2 = 4:1
