A spherical Gaussion surface encloses a charge of 8.85 * 10^-8C . If the radius of the Gaussian surface is doubled, how much flux would pass through the surface?

Deduce the expression of total flux Phi through a surface S.

A rectangular coil having 60 turns and area of 0.4m^2 is held at right angles to a uniform magnetic field of flux density 5×10^−5T. Calculate the magnetic flux passing through it.

Show that the electric flux through a closed surface S is q//in_0

What is the net electric flux through a closed surface surrounding an electric dipole? Derive the expressions for electric field intesity both inside and outside a uniformly charged spherical cell. What is the total enclosed by a closed surface if the electric flux entering and leaving the surface are 20000N/Cm^2 and 30000N/C m^2 respectively.

A charge Q µC is placed at the centre of a cube. The flux coming out from any surface is
