#### If the length of simple pendulum is increased by 44% then what is the change in the time period of the pendulum? Option 1) 22 % Option 2) 20 % Option 3) 33 % Option 4) 44 %

As discussed in

Time period of oscillation of simple pendulum -

- wherein

l = length of pendulum

g = acceleration due to gravity.

length increased by 44%.

New length

i.e. Time period increased by 0.2 or 20%

Option 1)

22 %

This solution is incorrect.

Option 2)

20 %

This solution is correct.

Option 3)

33 %

This solution is incorrect.

Option 4)

44 %

This solution is incorrect.
