Useful constants: Coulomb's constant k = 8.99 x 109 N m2/C2, co = 8.85 x 10-12 C2/N m2. Part A 5 pts A charge of Q = 2.3 microC is placed at the center of a regular tetrahedron all of whose sides are 2.4 m long. What is the electric flux through one side of the tetrahedron? (A regular tetrahedron is an object all of whose 4 sides are equilateral triangles. It is similar to a pyramid, but with a triangular base.) 65000 (N*m^2/c) (in (N*m^2/C)) OA: 31200 OB: 43300 OC: 65000 OD: 86600 OE: 96100 OF: 108000 OG: 130000 OH: 260000 Computer's answer now shown above.
