. A solid sphere of uniform density and radius 4 units is located with its centre at the origin O of coordinates. Two spheres of equal radii 1 unit, with their centres at A (2,0,0) and B (2,0,0), respectively, are taken out of the solid leaving behind spherical cavities as shown in the figure. Find the ratio of the magnitude of electric field at point A and B a) 1754 b) 1854 c) 1834 d) 2134 For solid sphere, Field inside sphere, E r3 0 And field outside sphere, E r 3 3r 2 0. .
Then,. Fundamentals of Physics EXP-2928 An insulating solid sphere of radius a has a uniform volume charge density p and carries a total positive charge Q (Fig. 1. Fundamentals of Physics EXP-2928 An insulating solid sphere of radius a has a uniform volume charge density p and carries a total positive charge Q (Fig. . . 11). .
