Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

An object is tied to a string and whirled in a horizontal circle at constant speed. For this object, the centripetal force is provided by Which one is correct ?

An object is tied to a string and whirled in a
horizontal circle at constant speed. For this
object, the centripetal force is provided by
the tension in the string
O the normal force
the object's weight
the tension in the string and the object's

Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
