Question

Margie, who weighs 428 N, is standing on a bathroom scale that weighs 55.0 N.

With what magnitude force does the floor push up on the scale?

Answer 1

To find the magnitude force with which the floor pushes up on the scale, we need to subtract the weight of the scale from the weight of Margie.

Margie weighs 428 N and the scale weighs 55.0 N. Therefore, the net force acting on the scale is:

Net force = Margie's weight - Scale's weight

Net force = 428 N - 55.0 N

Net force = 373 N

So, the magnitude force with which the floor pushes up on the scale is 373 N.
