roblems z3.1 An uncharged metal sphere, A, is on an insulated base. A second sphere, B, of the same shape, size and material carrying (a) Describe what happens to charges on spheres A and B as b) If we now remove sphere B and place it far away, what is the a charge +Q is brought into contact with sphere A. they are brought into contact. charge on sphere A? 9) How is this charge (if any) distributed? 23.2 An uncharged sphere, second sphere, B, of the same shape, size and material carrying ed metal sphere, A, is on an insulated base. A a charge +Q is brought close to, but not touching, sphere A Describe what happens to the charges on spheres A and B as they are brought close together but not touching. (a) (b) If we now remove sphere B, what is the charge on sphere A? (c) How is this charge (if any) distributed?Explanation / Answer
Q.1 a) Spheres A and B will both acquire charges Q/2 , implying charges will flow from B to A.
b)Same charge Q/2
c) The charge will distribute uniformly over sphere A. (Q/2)
Q.2
a) Sphere A will acquire - Q ( opposite of + Q ) on the side facing sphere B.
b)Once sphere B is removed, A will again get back to the neutral state.
c) -ve charges will spread uniformly over the surface of sphere A.
