What could be the reason a car moving on a horizontal road gets thrown out of the road while taking a turn?
Correct answer: D. Due to lack of sufficient centripetal force
- A. Due to the reaction between the car and ground
- B. Due to rolling frictional force between tyre and road
- C. By the gravitational force
- D. Due to lack of sufficient centripetal force
Explanation
Fact: When an object takes a turn two forces come to act.Centripetal forceCentrifugal forceCentripetal force acts inward (towards the centre of the circular turn). This is provided by tile frictional force. When the speed is large, required centripetal force to stay in the circular path increases. But friction is unable to provide large centripetal force and hence the body is thrown outwards.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
