Q1. A thin metallic spherical shell contains a charge Q on it.A point charge q is placed at the centre of the shell and another charge q 1 is placed outside it.All the three charges are positive.The force on the charge at the centre (a)towards left (b)towards right (c)upwaed (d)zero Q2.Consider the situation of the previous problem the force on the central charge due to the shell is (a)towards left (b)towards right (c)upward (d)zero Pliz explain the result!!!
