Assertion A particle is roting in a circle of radius 1 m. At some given instant, its speed is `2 ms^(-1)`. Then acceleration of particle at the given instant is `4 ms^(-2)`.
Reason Centripetal acceleration at this instant is `4 ms^(-2)` towards centre of circle.

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
`a_(c)=(v^(2))/(R)=((2)^(2))/(1)=4ms^(-2)`
But no information is given for tangential acceleration `a_(t)`.
