19. Given below are two statements: Statement I: An electric dipole is placed at the centre of a hollow sphere. The flux of electric field through the sphere is zero but the electric field is not zero anywhere in the sphere. Statement II: If R is the radius of a solid metallic sphere and Q be the total charge on it. The electric field at any point on the spherical surface of radius r ( (A) 2 3 4 5 t(s) (B) 0 (C) 1 2 345 t(s) (D) 3 4 5 t(s) 2 3 4 5 t(s)
