AI Thread Summary
To determine the external energy required to position a charge at the center of a square formed by four identical point charges, one must consider the work done against the electric field created by the existing charges. The voltage at the center of the square, influenced by the four corner charges, plays a crucial role in calculating this energy. The relationship between work and voltage indicates that the energy needed is equal to the charge multiplied by the voltage at that point. Understanding these principles is essential for solving the problem effectively. The discussion emphasizes the importance of applying electrostatic concepts to find the required energy.

hey guyz, this Q is pretty hard. I think.

Identical point charges (+50uC) are placed at the corners of a square with sides of 2.0-m length. How much external energy is required to bring a fifth identical charge from infinity to the geometric center of the square?

Well,what did u do...?It's not that hard...

What is the relationship between the work done to move a charge to point A from infinity and the voltage at point A relative to infinity?
 

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}...
