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 object.
(a) What is the electric flux through the base?
(b) What is the electric flux through each of the three sides?
ATTEMPT:
for part a i used flux=EA. for A i used BH/2 and got .0173. i multiplied that by 200 and got 3.46 m^2/C. can someone verify this is correct?
for part b i just divided that number by 3 because the total flux in the sides must equal that of the base so i got -1.1533m^2/C. i think the sign is negative because it must have the opposite sign of the base. is this right?
