Question

Assertion :The time period of a simple pendulum is independent of its length. Reason: The length of a pendulum is the distance between point of suspension and centre of the bob
  1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
  2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  3. Assertion is correct but Reason is incorrect
  4. Assertion is incorrect but Reason is correct

A
Assertion is correct but Reason is incorrect
B
Assertion is incorrect but Reason is correct
C
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
D
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Solution
Verified by Toppr

The time period of a simple pendulum is given by ,
T=2πl/g ,
where l= distance between point of suspension and center of bob (center of gravity)
It is clear that time period T of simple pendulum depends on its length l , hence assertion is incorrect but reason is correct .
