A cyclist bends while taking turn to

(A): A cyclist leans inwards while taking a turn, while a man sitting in a car leans outwards on a curve. (R) : Centripetal acceleration is acting towards the centre of the curve.

The inward bending of a cyclist while turning is due to

A cyclist taking turn bends inwards while a car passenger taking same turn is thrown outwards. The reason is

STATEMENT -1 : A cyclist has to bend while traversing a turn on a horizontal road . and STATEMENT -2: Normal force acting on the tyres of bicycle has horizontal component , ( which provides the necessary centripetal force ) only when cycle is bent

(A) : A player lowers his hands while catching a cricket ball. (r) : Increase in the time of action of force, decreases the impulsive force.

A stone of mass m tied to the end of a string, is whirled around in a horizontal circle. (Neglect the force due to gravity). The length of the string is reduced gradually keeping the angular momentum of the stone about the centre of the circle constant. Then, the tension in the string is given by T = Ar^n where A is a constant, r is the instantaneous radius of the circle and n=....
