Question

Directions: These questions consists of two statements each printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses
Assertion: In case of projectile motion, the magnitude of rate of change of velocity is variable.
Reason : In projectile motion, magnitude of velocity first decreases and then increases during the motion.

Moderate

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
C

If Assertion is correct but Reason is incorrect.
D

If Assertion is incorrect but Reason is correct.

Solution

$|\frac{d v}{d t}| = | a | = 9.8 {ms}^{- 2}$ constant and it is true that in case of projectile motion, the magnitude of velocity first decreases and then increases during the motion.
