Conducting Conducting spheres Electrostatic Electrostatic equilibrium Equilibrium Spheres

AI Thread Summary

The discussion revolves around solving a homework problem related to conducting spheres in electrostatic equilibrium. The user applied the equation for electric potential and the conservation of charge to find the charge on one of the spheres. However, their calculated value for q3 was incorrect, yielding 0.0002 instead of the expected 2.06*10^-4. The user seeks assistance to resolve this discrepancy in their solution. Clarification on the application of the equations and the conditions for electrostatic equilibrium is needed to arrive at the correct answer.

Homework Statement

Homework Equations

potential, V = kq/r where k is 1/4 pi epsilon

conservation of charge, sum of q = Q

The Attempt at a Solution

what i did is let q1 + q2 + q3 = 4*10^-4

then let V1 = V2 = V3 and solve for q3

but i end up getting q3 = 0.0002 which is not the correct ans, which is c, 2.06*10^-4

any help? much appreciated!

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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 '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...
