A grounded sphere of 2 mm radius is placed in the centre of a 10mm x 10mm x 10mm box. 5 point charges, -2C, -1C, 1C, 2C, 3C are placed at random positions on the z = 0 plane in the box (outside the sphere). Draw the charges (color coded), E field lines and Potential distribution on the z = 0 plane. (Positions of the charges can be taken of your choice.) (Make proper color mapping for each charges, field lines.)
