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.

Options

A. If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C. If Assertion is true, true but the Reason is false.
D. If Assertion is false but the Reason is true.

Answer

A

Explanation

At ` A`
Tangential acceleration is `g` . Radial acceleration is
`(v^(2))/(R)` .
:. `a_(n et)=sqrt(g^(2)+((v^(2))/(R))^(2))`
