Question

The time periods of two pendulums are 1.44 s and 0.36 s respectively. Find the ratio of their lengths.

Answer 1

Answer:

Hey mate here is your answer.//

Explanation:

T= 2л√l/g,

T∝√l ..(since rest of the terms in the equation are constant)

Thus,

T1/T2=√l1/l2,

T12/T22=l1/l2,

l1/l2=(1.44)²/(0.36)²,

2.073/0.129

=16/1

So, the ratio of the lengths is 16:1.
