Question

A particle is moving in a circular path with decreasing speed, then for this situation mark out the correct statement(s)

• A. The radical component of its acceleration is decreasing in magnitude
• B. The angular speed of the particle will decreasing.
• C. Tangential components of acceleration and velocity are in opposite directions.
• D. The particle is performing a non-uniform circular motion

Answer 1

Answer: (A), (B), (C), (D)

The particle is performing a non-uniform circular motion

Circular motion:

1. If any particular particle is moving in circular motion with decreasing speed, then the magnitude of the radial component of acceleration is diminishing.
2. If any particular particle is moving in circular motion with decreasing speed, then angular speed of the particular will decrease.
3. Velocity and tangential components of acceleration move in opposite direction if any particular particle is moving in circular motion with decreasing speed.
4. Particle will show non-uniform circular motion, if any particular particle is moving in circular motion with decreasing speed.

Hence, option a, b, c, d are correct answer.
