When a body is whirled in a horizontal circle by means of a string the centripetal force is supplied by:

Correct answer: B. Tension in the string

  • A. Mass of body
  • B. Tension in the string
  • C. Velocity of body
  • D. Centripetal acceleration

Explanation

Therefore, the correct answer is option B: Tension in the string. The centripetal force required to keep the body moving in a horizontal circle is supplied by the tension in the string, which acts as an inward force, pulling the body towards the center of the circle.

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.
