Kinematics Question 477
Question: Assertion: A safe turn by a cyclist should neither be fast nor sharp. Reason: The bending angle from the vertical would decrease with increase in velocity.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.

Answer:
Correct Answer: C
Solution:
For safe turn $ \tan \theta \ge \frac{v^{2}}{rg}. $
It’s clear that for safe turn v should be small and r should be large. Also bending angle from the vertical would increase with increase in velocity.
