i have a doubt on this one. we know +ve charge (proton) and neutrons make the most of mass for any matter. Now consider a conductor and through induction, centre of -ve charged is moved toward the object (insulator(static charge on it) with +ve charge say). Now these two attract and conducting object get attracted to +ve charged insulator. question is that this conducting object should move according to the force on +ve charge not according to -ve charge. so this conductor should get repelled? give justification where i am getting wrong?
