A tetrahedron has an equilateral triangle base with 20-cm-long edges and three equilateral triangle sides. The base is parallel to the ground, and a vertical uniform electric field of strength 200 N/C passes upward through the tetrahedron.
What is the electric flux through the base?

electric flux through the base is 3.45 m²/C

Explanation:

given data

base length = 20 cm

uniform electric field of strength = 200 N/C

solution

as base is perpendicular to filed flux through the base

Ф = - × E × a² .......................1

here E is strength of electric field and a is side

so put here value in equation 1 we get

Ф = - × 200 × 0.20²

Ф =  3.45 m²/C

so electric flux through the base is 3.45 m²/C

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
