Assertion : When a cyclist doubles his speed of turning, the chance of his skidding becomes nearly four times. Reason: When the speed of the vehicle increases, the angle of bending also increases.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

For the banking of curve, = v^2 r g . When velocity v is doubled, becomes four times. With increase in , the chance of overturning also increases. When v increases, increases and consequently chance of skidding or overturning becomes greater.
