Question

Assertion: On a rainy day it is difficult to drive a car or bus at high speed.
Reason: The value of coefficient of friction is lowered due to wetting of the surface.

• A. Both Assertion and Reason are correct and Reasion is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reasion is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reasion is the correct explanation for Assertion

The value of coefficient of friction is lowered due to wetting of the surface. Hence the frictional force becomes less and vehicle takes longer to stop after sliding for some distance.
