1 Answer
(1)
(5)
Explanation:
(1). Normal reaction
Frictional force
Net force
Acceleration of
or
(2). Let us examine what is the force acting on
We know that action and reaction are equal and opposite. Hence, there will be a reaction of
(3). For an applied force of
There is no change of force of friction. Hence, there is no change in the reaction force on
(4). Assuming that pulleys are friction-less, these are used to change the direction of applied force. The magnitude remains the same.
(5). By the same logic applied as in (4). above
