Roads are banked on curves so that

A

The speeding vehicles may not fall outwards

B

The frictional force between the road and vehicle may be decreased

C

The wear and tear of tyres may be avoided

D

The weight of the vehicle may be decreased

Text Solution

Verified by Experts

The correct Answer is:
A
By doing so component of weight of vehicle provides centripetal force and therefore speeding vehicles may not fall outwards.
