50. A couple produces
[1997]
(a) no motion
(b) purely linear motion
(c) purely rotational motion
(d) linear and rotational
Show Answer
Answer:
Correct Answer: 50. (c)
Solution:
- (c) A couple is formed of two equal and opposite forces at some separation; so net force is zero. Hence, a couple does not produce translatory motion; but it causes change in rotational motion.
