Rotational Kinematics & Dynamics question from MHT CET 2023 (11 May, Shift 1)

Answer: (c)

1. Speed decreases, so there is a tangential acceleration too; the resultant acceleration is not towards the centre.
2. The path is still the given circle, not a spiral.
3. $L = mvr$ decreases in magnitude, but $\vec{L}$ always points perpendicular to the plane of the circle.
4. So the answer is (c): the direction of angular momentum stays constant.
