Question

. Find the missing valus Base. Height Ares of triangle a) 40 cm-540.cm2.
b)
30 cm. 903.6 cm2.​

Answer 1

Answer:

To start with I do not see any picture related to this question so I am going to make an assumption

That the charges form a point charge.

That the enclosing surface is a regular Tetrahedron with equilateral triangle faces.

That the charge is equidistance from all triangular faces.

If we think of one of the faces as an infinite planar surface a certain distance d from the charge, then the flux through the plane is Θ=−6q/(2ℇo) . see the justification for this here Electric flux through an infinite plane due to point charge.

Since there are 4 planar surfaces then the flux through each plane is additive. Therefore 4 Θ =4( −6q/(2ℇo))=−24q/(2ℇo)

This seems pretty straight forward so I hope I am not missing something.
