Assertion : When a particle moves in a circle with a uniform speed, its velocity and acceleration both changes
Reason : The centripetal acceleration in circular motion is dependent on angular velocity of the body

Options

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

Answer

B

Explanation

In uniform circular motion, the magnitude of velocity and acceleration remains same, but due to change in direction of motion, the direction of velocity and acceleration changes. Also the centripetal acceleration is given by `a = omega ^(2) r`
