Know the formula for electric flux.
• The Electric Flux through a surface A is equal to the dot product of the electric field and area vectors E and A.[1]
• The dot product of two vectors is equal to the product of their respective magnitudes multiplied by the cosine of the angle between them.

2
Determine the magnitude and direction of your electric field vector.In most cases of this type, it is already given in the problem.
• 3
Determine the magnitude and direction of the surface area vector A.
• Note that the surface area vector is always perpendicular and outward from the surface.

Use unitary method For 4pi steradians which is the maximum possible solid angle in a cone, flux is given by gauss law =Qinside ÷EnotThe use unitary method inorder to find flux due to that much part of cone through which flux is to be ascertained.The conversion for solid angle and plane angle isPlane angle=2pi (1-cos@÷2) where @ is the plane angle
