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 (< R) is zero but the electric flux passing through this closed spherical surface of radius r is not zero. In the light of the above statements, choose the correct answer from the options given below:

Eight charges, 1muC, -7muC , -4muC, 10muC, 2muC, -5muC, -3muC, and 6muC`, are situated at the eight corners of a cube of side 20 cm. A spherical surface of radius 80 cm encloses this cube. The center of the sphere coincides with the center of the cube. Then, the total outgoing flux from the spherical surface (in units of Vm) is

the surface density of conducting sphere is 7.7 into 10 to the power minus 10 coulomb per metre square and electric field intensity at a distance of 4 m from the centre of the sphere is 2 into 10 to the power minus 2 volt metre find the radius of the sphere assuming the sphere to be vacuum.
