Linear velocity or tangential velocity of any particle moving in a circular path of radius 2m with angular velocity 8rad-1 will be:
Correct answer: A. 16ms-1
- A. 16ms-1
- B. 10ms-1
- C. 4ms-1
- D. 6ms-1
Explanation
The linear velocity (also known as tangential velocity) of a particle moving in a circular path with a radius of 2 meters and an angular velocity of 8 radians per second is calculated using the formula: v = r * ω. Substituting the values, we get v = 2m * 8rad-1 = 16ms-1. Therefore, the correct answer is Option A. Options B, C, and D are incorrect because they do not correctly apply the formula for calculating linear velocity in circular motion.

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.
