Question

When a cyclist bends in order to take a turn, which of the following provide the extra centripetal force required?

• A. Friction
• B. Normal reaction
• C. Weight of the cyclist
• D. None of these

Answer 1

The correct option is B Normal reaction

When a cyclist bends to take a turn, the direction of action of the normal reaction bends along with the cyclist.

This produces an additional component of the normal reaction along the radius of the turn towards the centre. This force provides the extra centripetal force.
