If you are pushing on a box with a force of 20 n and there is a force of 7 n on the box due to sliding friction, what is the net force on the box? i need the answer asap!

Net force acting on the box,

Explanation:

It is given that,

Force with which the box is pushed, F = 20 N

Force acting due to sliding friction, f = 7 N

Sliding friction is a type of resistive force. It always opposes the motion of an object. Here, the force of 7 N will act in the opposite direction of motion. As a result, the net force acting on the box is given by :

So, the net force acting on the box is 13 N. Hence, this is the required solution.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
