A cyclist bends while taking turn to

A

reduce friction

B

generate required centripetal force

C

reduce apparent weight

D

reduce speed

Text Solution

Verified by Experts

The correct Answer is:
B
Turning means motion on a curved path, which requires centripetal force. Bending of cyclist, with respect to vertical, direction provides the necessary centripetal force.

    the cycle moves slower than the car
    C
    the car moves faster then the cycle
    D
    cyclist counteracts the centrifugal force, which throws the passegers in the car outwards
