Charge Electric Electric field Field Work Work done

AI Thread Summary

The discussion focuses on calculating the work done on a charge "q" by an electric field "E" when moved a distance "d." The solution provided uses the integral form of work, leading to the equation W = qEd, which is derived from the Lorentz force equation. The contributor expresses uncertainty about the relevance of the mass "m" in the calculation but concludes that it is not necessary for this specific problem. Overall, the approach appears correct, and the calculation aligns with the principles of electrostatics. The conversation emphasizes understanding the relationship between electric force and work done in electric fields.

Homework Statement

Find the work done a charge "q" of mass "m" by an electric field of magnitude "E" when it's moved a distance "d"

2. The attempt at a solution

W = \int_A^B F_e \cdot dr = F_e \int_A^B dr = F_e d = qEd

I used the Lorentz force equation for electrostatics at the end. I'm not sure if I did it correctly. I never used the mass given but I'm pretty sure I don't need it.

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...

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...
