What is the outward force acting on a mass of 10 kg when rotating at one end of an inelastic string 10 m long at a speed of 1 m/s?
Correct answer: B. 10N
- A. 1N
- B. 10N
- C. 2N
- D. 100N
Explanation
The outward force acting on a rotating mass is the tension in the string, which is equal to the centripetal force. This force is given by \( F = \frac{mv^2}{r} \), where \( m \) is the mass, \( v \) is the speed, and \( r \) is the radius.

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.
