- Homework Statement
- Induced charge inside a metal conductor infinitely bounded due to a positive charge q kept beside it is -q(1-1/k).

- Relevant Equations
- None

Following the above statement my teacher was trying to prove something and it started with suppose q1 and q2 are charges placed in a medium (k) of infinite expanse. The distance between them being r. He took q1 and q2 to be some spherical particles and not point charges and concluded that

Net force on q1= Force due to q2 + force due to Induced charges in q2 + force due to induced charges in q1.

Firstly I dont understand why Induced charges will have a different force (?) I dont even understand induction mathematically I think.

Secondly If I pretend that I understand it , the force due to Induced charges in q2 is said to be -q2 (1-1/k) but shouldn't it be -q1(1-1/k)??? Since the other charge is responsible for creating the induction.....
