# Solution - If the Metal Bob of a Simple Pendulum is Replaced by a Wooden Bob of the Same Size, Then What is Effect on Time Period - HSC Science (Electronics) 12th Board Exam - Physics

ConceptSome Systems Executing Simple Harmonic Motion

#### Question

If the metal bob of a simple pendulum is replaced by a wooden bob of the same size, then its time period will.....................

1. increase
2. remain same
3. decrease
4. first increase and then decrease.

#### Solution

(b) remain same

The time period of a simple pendulum is

T=2pisqrt(l/g)

where l = length of the pendulum

g = acceleration due to gravity

Therefore, from the given equation, we know that the periodic time of the pendulum does not depend on the mass of the bob, and so, it does not matter of what material the bob is made of, and hence, its time period remains the same.

Is there an error in this question or solution?
