For a particle in uniform circular motion the relation a=rα of acceleration hold. The acceleration 'a'
Correct answer: B. Is tangental acceleration
- A. Is centripetal acceleration
- B. Is tangental acceleration
- C. Is radial acceleration
- D. Both A and B
Explanation
Explanation is given below: In uniform circular motion, the relationship between acceleration (a), radius (r), and angular acceleration (α) is given by the equation: a = r * α Here's what each variable represents: "a" is the magnitude of the linear acceleration of the particle (the acceleration in the direction of motion). "r" is the radius of the circular path. "α" is the magnitude of the angular acceleration (the rate of change of angular velocity). This equation tells us that the linear acceleration of a particle in uniform circular motion is directly proportional to the radius of the circular path and the angular acceleration. In other words, the particle's linear acceleration is directed towards the center of the circle and is proportional to both the radius of the circle and the angular acceleration.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
