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:

Answer:

Solution:

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