Question

Assertion: A car moving on a horizontal rough road with velocity v can be stopped in a minimum distance d . If the same car, moving with same speed v takes a circular turn, then minimum safe radius can be 2 d . Reason: d = 2 μg v 2 ​ and minimum safe radius = μg v 2 ​ .

TestHub · Accepted Answer

Minimum stopping distance: 0 = v 2 − 2 ( μg ) d gives d = 2 μg v 2 ​ . Minimum safe turning radius: μ m g = r m v 2 ​ gives r = μg v 2 ​ = 2 d (Assertion true). The Reason states exactly these two relations, so it is true and correctly explains the Assertion.
