Conducting Spheres in Electrostatic Equilibrium

Click For Summary
SUMMARY

The discussion focuses on solving a problem involving three conductive spheres in electrostatic equilibrium. The user applied the formula for electric potential, V = kq/r, and the conservation of charge principle, summing charges to 4 x 10^-4 C. Despite setting V1 = V2 = V3 and calculating q3, the user arrived at an incorrect value of 0.0002 C instead of the correct answer of 2.06 x 10^-4 C. The error in the calculation needs to be addressed to reach the correct solution.

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
