Question 5: Properties of Matter

Question

Assertion :
Sometimes insects can walk on
water.
Reason :
The gravitational force on insect is
balanced by force due surface tension.

Accepted Answer

Sometimes, insects can walk on the surface of
water due to surface tension, when legs of insects
are not being wet. In this situation, the
gravitational force on insect is balanced by force
due to surface tension.
Hence, both assertion and reason are true and
reason is correct explanation of assertion.
