Apush of magnitude p acts on a box of weight w as shown in the figure. the push is directed at an angle θ below the horizontal, and the box remains a rest. the box rests on a horizontal surface that has some friction with the box. the friction force on the box due to the floor is equal to

Explanation:

Since applied force is at an angle with the horizontal so we can find the two components of the force on it

now the normal force due to floor is given as

Also we know that the box is not moving but it remains at rest

so here we can say that friction force due to floor will counterbalance the horizontal applied force on the box

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
