COMEDK · Physics · 5. Laws of Motion
If no external force acts on particle, then which of the following statement is incorrect about particle?
- A Particle may be at rest.
- B Particle moves with uniform velocity on linear path.
- C Particle moves with uniform speed on circle.
- D None of the above
Answer & Solution
Correct Answer
(C) Particle moves with uniform speed on circle.
Step-by-step Solution
Detailed explanation
The statement given in option (3) is incorrect and it can be corrected as, When particle moves in a circle even with uniform or constant speed, it faces an external force towards its centre called centripetal force.
