Question

find the flux through the surface of a equillateral cone

Jyoti Pant · Accepted Answer

Here, the flux is equal to the product of the magnitude of the
field and the total surface area The flux will be given
by,

Electric flux=Electric field x Area
Surface area of cone is given by,
πr(l+r)For equilateral cone side or slant height 'l' is equal to
the diameter of the base i e l=2rSo, A=π
r(2r+r)=3r×πr=3πr2Thus,Flux,
Ï•=E×3πr2

find the flux through the surface of a equillateral cone.
