Question

the 2 and the 3 questions .... please ....

Answer 1

the graph between U and x is parabola

Answer 2

1. If two forces act on a body in the same direction, the result is that the magnitude of the net force acting on the body is the sum of the magnitudes of these two forces.

In case the lines of action of these two forces are not the same then it is possible that in some cases there may be a torque generated, the magnitude and direction of which would depend on the distance of these two forces from the axis of rotation.

Hence, net force is the addition of forces.

2. Graph would be parabola .
