PhysicsMediumassertion reason

Assertion: In uniform circular motion, the dot product of velocity and acceleration is zero.

Reason: In uniform circular motion, the tangential acceleration is zero.

Answer:

Solution:

$v \cdot a = v a_{t} = 0$ since $a_{t} = 0$ in uniform circular motion.
Both are true and the Reason explains the Assertion.
