Question

A car is taking a turn on a level road. It may be thrown outwards because of the

• A. reaction of the ground.
• B. frictional force.
• C. weight of the car.
• D. lack of centripetal force.

Answer 1

Answer: (D)

lack of centripetal force.

Centripetal force is necessary for circular motion for any particle. If the particle does not get centripetal force, it will leave the circle and move along the the tangent due to inertia of direction. In motion of car, friction provides the necessary centripetal force, and lack of it will cause it to be thrown outside.
Note: Here friction is not the reason for car to be thrown outside, it is the reason for circular motion. but lack of it surely will be a reason for thrown outside.
