Question

if the length of a simple pendulum is double what will be the change in it's time period?​

Answer 1

Answer:a) If the length is doubled, the period will increase by a factor of √2 . Doubling the mass of the bob will half the period.

Answer 2

Answer:

If the length of a simple pendulum is double , then it's time period will increase with the factor of √2 or 1.414

Explanation:

Lets assume that the amplitude is << 1 rad.

Time period T = 2 π √(L/g) where L is length

Now when length is doubled then

Time period = 2 π √(2L/g)

Which is equal to √(2)T , which means the period is increased by roo

√(2) times the previous time period.
