Electric Charges & Fields | Gauss Law All the best! 1. An electric dipole of dipole moment p is enclosed in a hollow sphere of radius R (R > ℓ) where l is length of dipole. The flux through the surface is- A. Zero B. (4πR2) x p C. p / ℓεo D. p / 2ℓεo Option (A) Option (B) Option (C) Option (D) None 2. A charge Q is enclosed by a Gaussian spherical surface of radius R. If the radius is doubled, then the outward electric flux will- be doubled increases four times be reduced to half remain the same None 3. A charge of 20 μC is enclosed by a spherical Gaussian surface of radius 10 cm. If the radius is doubled, then outward electric flux will- be doubled be reduced to half increases four times remains the same None 4. Some point charges are enclosed by four closed surfaces S1, S2, S3 and S4 as shown in the figures. The ratio of areas of these surfaces are 1:2:3:4. The electric flux through the surface S1 is maximum and S4 is minimum S2 is maximum S4 is maximum is the same for all the figures None 5. There is a point charge +Q inside a hollow sphere and a point charge -Q outside its surface. The total flux passing through the sphere is- -Q/εo Q/εo zero 2Q/εo None 6. A charge Q is placed at the center of a cube. The electric flux through one of its faces is- Q/εo Q/6εo Q/8εo Q/3εo None 7. What is the electric flux through a cube of side 'a' if a point charge Q is at one of its corners? Q/εo Q/2εo Q/6εo Q/8εo None 1 out of 7 Time's up
