What Forces Are Not Exerted on a Bathroom Scale?

  • Thread starter Thread starter Mike Hunt

AI Thread Summary
The discussion revolves around identifying which force is not exerted on a bathroom scale when a person stands on it. The options include contact forces from the floor and the person's feet, the person's weight, and the weight of the scale itself. Participants attempted various combinations but found none of their selections correct. A suggestion was made to draw a free body diagram to better analyze the forces acting on the scale. Understanding the forces involved is crucial for solving the problem accurately.

Homework Statement



A person is standing on a bathroom scale. Which of the following is not a force exerted on the scale?

A) A contact force due to the floor
B) A contact force due to the person's feet
C) The weight of the person
D) The weight of the scale


The Attempt at a Solution



They are check boxes. I have tried A. I have tried D. I have tried both A and D. None of those answer combinations are right.

Draw a free body diagram of the scale, and examine the forces acting on it. Now see which one(s) do not apply.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
