Question

when does a body start moving?
(a) when frictional force is bigger
(b) when frictional force is smaller
(c) when pushing force is larger than friction
(d) all of the above​

Answer 1

Answer:

Option d is your answer

All of the above

Answer 2

Answer:(b)

Explanation:if the friction force is larger then it creates obstacle in the path... if friction force is smaller it's not necessary that the pushing force is greater,it may be balanced.... but when the pushing force is greater than the friction force then, no obstacle, no resistance in the path, thus the objects move
