NEET Physics Circular Motion Dynamics Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Centripetal force | (i) Gravitational force on block |
| (b) Action-reaction pair | (ii) Self-adjusting force |
| (c) Static friction | (iii) Force providing inward acceleration |
| (d) Force on the floor | (iv) Action of block on the floor |
a-iii, b-i, c-ii, d-iv
a-ii, b-iii, c-i, d-iv
a-i, b-iv, c-iii, d-ii
a-iii, b-ii, c-iv, d-i
Correct Answer
Detailed Explanation
Centripetal force is defined as the force providing inward radial acceleration to a body in circular motion. The action-reaction pairs include the gravitational force on the block and the force exerted by the block on the earth. Static friction acts as a self-adjusting force up to its limit, and the force on the floor is the action of the block on the floor.
