A body is revolving with a uniform speed ' (v ) ' in a circle of radius ' (r ) '. The tangential acceleration is:

Options

  1. A( v r )
  2. B( v² r )
  3. C( v r ² )
  4. Dzero

Correct answer

D. zero

Step-by-step solution

when a body is revolving around a circular path, it experiences 2 forces: Centrifugal force and Centripetal Force. Centrifugal force (Latin for 'center fleeing') describes the tendency of an object following a curved path to fly outwards, away from the center of the curve. It's not really a force; it results from inertia (- ) the tendency of an object to resist any change in its state of rest or motion. Centripetal force is a real force that counteracts the centrifugal force and prevents the object from 'flying out
