There are two charges with charge q and mass m

AI Thread Summary
In the discussion, the concept of equilibrium is clarified, emphasizing that it means the net force acting on the charges is zero. The relationship between electrostatic force and gravitational force is highlighted, with the teacher indicating that the electrostatic force (F) equals the gravitational force (mg) when the charges are in equilibrium. Participants are encouraged to consider all forces acting on the particles in the diagram for a complete analysis. The importance of vector addition in visualizing the forces is also mentioned. Understanding these principles is crucial for solving problems related to charged particles in equilibrium.

There are two charges with charge q and mass m and they are in equilibrium. Then, in the diagram why is my teacher saying that electrostatic force(F)=mg? Below is diagram.

OK, you've started with a diagram that correctly shows the gravity force and the electric force. It might help to also show any other forces acting on the particle.

What does "equilibrium" mean in terms of the forces?
 
Equilibrium means net force is zero, right?

Yes. That's right. If you added (head-to-tail) the force vectors acting on the particle, what would the diagram look like?
 

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}...
