Physics - SHM Question with Solution | TestHub
Match the following List-I with List-II:
List-I | List-II |
|---|---|
(I) A bob B hanging from a string A of length is projected to left with a speed of
| (P) The acceleration of centre of mass of B at some time can be equal to g |
(II) The platform is pushed down by a distance below mean and released, where is compression in mean position
| (Q) The force exerted by A on B can be zero at some point |
(III) A spherical solid ball B is released on a perfectly rough spherical surface A as shown
| (R) The speed of the body B varies sinusoidaly with time when force exerted by A on B is not zero |
(IV) Block B is released on a smooth track A as shown
| (S) The motion of B is oscillatory |
| (T) The motion of B is periodic |
Options:
Answer:
Solution:
(I) String can go slack: force on B can be zero; acceleration can be g.
(II) Platform SHM: oscillatory, speed sinusoidal; acceleration can equal g, normal vanishes at amplitude .
(III) Rolling oscillation is periodic; contact never breaks; not sinusoidal at finite amplitude.
(IV) On smooth track the block can lose contact: force can be zero, acceleration can equal g.
(B) matches: I-P,Q; II-P,Q,R,S; III-P,S,T; IV-P,Q.
Answer: B
