A closed surface encloses an elec-tric dipole. What is the electric flux through the surface ?

A point charge of 2muC is placed at the centre of a cubic Gaussian surface of side 0.5 cm. What is the net flux through the surface? (Given varepsilon_0 , = 8.85x 10^-12C^2 /N/M^2 )

Careful measurement of the electric field at the surface of a black box Indicates that the net outward flux through the surface of the box is 8.0 xx 10^3Nm^2C : What is the net charge Inside the box?

Careful measurement of the electric field at the surface of a black box Indi-cates that the net outward flux through the surface of the box is 8.0 xx 10^3Nm^2C :- If the net outward flux through the surface of the box were zero, could you conclude that there were no charges Inside the box? Why or why not?

Imagine that a charge .q. is situated at the centre of a hollow cube. What is the electric flux through one side of the cube?

Name the theorem used to find the electric flux through a surface enclosing charge.

If the flux of the electric field through a closed surface is zero, then: (a)the electric field must be zero every-where on the surface (b)the total charge inside the surface must be zero (c)the electric field must be uniform throught the closed surface (d)the charge outside the surface must be zero

A rectangular surface of sides 10 cm and 15 cm is placed inside a uniform electric field of 25 Vm^(-1) , such that normal to the surface makes an angle of 60^(@) with the direction of electric field. The flux of electric field through the rectangular surface is
