Question

2. Suppose identical, neutral metal spheres A and B are insulated from their surroundings and touching each other. A positive charge is brought near but not touchingsphere A, and now the two spheres are slowly separated. Finally, the positive charge is removed. What charge will be left on sphere A and sphere B, respectively?

a)A is negative, B is negative, b)A is positive, B is positive ,c)A is neutral, B is positive, d)A in positive, B is neutral, e)A in negative, B is neutral, f)A is neutral, B is negative, g)A is negative, B is positive, h)A in neutral, B is neutral, i)A is positive, B is negative

Explanation / Answer

. A is negative, B is positive
That's because the positive charge draws some electrons from B into A; once B and A are separated, A retains the -ve charge and B has become +ve.
