Question

Find length of pendulum if period of 2.24 second​

Answer 1

• 3.50 metres

Given :

• Period : 2.24 seconds

To find :

• Length of the pendulum

Solution :

We know that,

• 
  `T = 2\pi (L)/(g) \\`

where

• T = Period
• L = Length
• g = acceleration due to gravity

Plugging in the values we have,

• 
  `2.24 = (2 * 3.14) (L)/(9.8) \\`
• 
  `L = (2.24 * 9.8)/(6.28) \\`
• 
  `L = (21.952)/(6.28) \\`
• 
  `L = 3.50m`

Therefore, the length of the pendulum with the period of 2.24 seconds would be 3.50 metres.
