Question

A car moving on a horizontal road may be thrown out of the road in taking a turn:

Options

• By the gravitational force.

• Due to the lack of proper centripetal force. 

• Due to the rolling frictional force between the tyre and road.

• Due to the reaction of the ground.

Answer 1

Due to the lack of proper centripetal force. 

Explanation - 

When a car makes a turn on a horizontal road, centripetal force is required. The frictional force is responsible for this. When the car's speed is high, though, the required centripetal force to turn increases. However, it gets thrown off the road due to a lack of sufficient frictional force.
