E
If Assertion is false but Reason is true.
Question 6
4 / -1

Assertion A negative acceleration of a body can be associated with a \'speeding up\' of the body.
Reason Increase in speed of a moving body is independent of its direction of motion.

A

E
If Assertion is false but Reason is true

Solution
Question 8
4 / -1
