AI Thread Summary
The discussion focuses on calculating the electric field at the center of an equilateral triangle with sides of uniform charge densities of 1 MC/m, 2 MC/m, and 3 MC/m, each measuring 50 cm. Participants note that the provided equations are not suitable for this problem, as they refer to infinite lines and planes of charge rather than the specific configuration of the triangle. It is suggested that integration over the lengths of the charged sides is necessary to find the electric field. The conversation also touches on personal circumstances affecting participation, such as power outages in Gaza. Overall, the thread emphasizes the need for proper integration techniques to solve the problem effectively.

You need to fill up this section properly. The equations you provided aren't particularly useful because the first one refers to an infinite line of charge, the 2nd one is for an infinite plane of charge. You have to integrate over the length of one of those lines of charge. Then you can use the result for the other two lines of charge to get the answer. Now, how would you set up such an integration?
 
Thank you very much attention to
I really do not need you, but I live in Palestine and the Gaza electricity cut off most of the time I came to you Valmalk
But Halit question to light the candle and thank God

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...
