When we charge a metal sphere negatively by bringing a positively charged rod near its left surface, the electrons get attracted towards the left side and positive charges on right side. Now, when the sphere is earthed the electrons from earth flow to the sphere to neutralise the positive charge collected on the right side. Now, when the positively charged rod is removed the negative charges get distributed over the metal surface and the sphere gets negatively charged.
