The discussion revolves around calculating the equilibrium distance between charged spheres, specifically focusing on two charged spheres at the ends of a pole and a third sphere positioned along that pole. The original poster describes the setup involving charges of different magnitudes and seeks to determine the distance from one of the spheres to the equilibrium position.
Some participants have offered hints regarding the calculation of electric fields and the possibility of treating the charge of the third sphere as a variable. The conversation reflects an exploration of different interpretations of the problem setup and the assumptions involved.
There is a noted uncertainty regarding the charge of the third sphere and its impact on determining the equilibrium position. The original poster's task is framed within the constraints of a homework assignment, which may impose specific rules or expectations for the solution process.
You don't need to know the charge on the third sphere to figure out the equilibrium point. (Just call it Q, if you like.)TROGLIO said:how can u solve it wothout knowing d charge of d 3rd sphere??
