A toy car of mass is maintained to move in a horizontal circle of radius with a velocity . If the centripetal force acting on it is , then the value of in is

Important Questions on Force








Reason (R): The trains have different centripetal accelerations due to different speeds.


A car of mass is revolving in a circular track of radius with angular velocity , then find the centripetal force in Newton.


A small block of mass is tied to a spring of spring constant and length The other end of spring is fixed at a particular point If the block moves in a circular path on a smooth horizontal surface with constant angular velocity about point then tension in the spring is

Compare the magnitudes of centripetal and centrifugal force.







Two stones of masses and are whirled in horizontal circles, the heavier one in radius and the lighter one in radius . The tangential speed of lighter stone is times that of the tangential speed of the heavier stone. They are reported to experience the same centripetal force. The value of is,
