AIIMS 2019 Physics Simple Pendulum MCQ Question
Assertion : The percentage change in time period is 1.5%, if the length of simple pendulum increases by 3%.
Reason : Time period is directly proportional to length of pendulum.
If both assertion and reason are true and reason is correct explanation of assertion.
If both assertion and reason are true and reason is not correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
In the given problem, the relationship between the time period of a simple pendulum and its length is expressed as . The formula indicates that a 3% increase in length results in a 1.5% increase in the time period, confirming that option C accurately reflects this calculation. Other options are not applicable as they do not provide relevant information or calculations related to the problem. Understanding this relationship is crucial for analyzing how changes in length affect the oscillation period of a pendulum.
