Question

10. Assertion: If an unbalanced force is applied on the object, there will be no change either in
its speed or in the direction of its motion,
Reason: To accelerate the motion of an object, an unbalanced force is required.
(1)
11. Assertion: Uniform circular motion is not an accelerated motion,
Reason: In uniform circular motion, body changes its direction continuously.
(1)​

Answer 1

Answer:

10 assertion is false but reason is true

11 assertion is false but reason is true

Explanation:

10 according to Newton's law,an object at rest will stay at rest until an UNBALANCED force acts on it hence assertion is false and reason is true

11 uniform circular motion is an accelerated motion since radial/centrepetal acceleration acts on the body undergoing circular motion at all times and constantly changes its direction hence assertion is false and reason is true
