Question

Assertion :In vertical circular motion, acceleration of bob at position A is greater than '$g$' Reason: Net acceleration at A is resultant of tangential and radial components of acceleration.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion is incorrect and Reason is correct

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

In vertical circular motion, there is always a downward acceleration of g due to gravity. The acceleration of bob at point 'A' is resultant of tangential and radial acceleration. This net acceleration can be broken down in horizontal and vertical components and thus it would always be more than g which is a compulsory vertical downward component. Hence, assertion and reason both are correct and reason is a correct explanation of the assertion.
