Question

A pendulum has a period of 5 seconds. If the length of the string of the pendulum is quadrupled, what is

the new period of the pendulum?

g=10ms2​

Answer 1

Answer:

10 sec

Explanation:

Given Data

T= 5 sec

L= 4L

New Tn=?

Solution :

T= 2π√(L/g)

Tn = 2π√(4L/g)

Tn = 2π(2√(L/g))

Tn = 2( 2π√(L/g) )

Tn = 2 ( T )

Tn = 2( 5 )

Tn = 10 sec
