Answer:
electric flux through the three side = 2.35 N m²/C
Explanation:
given,
equilateral triangle of base = 25 cm
electric field strength = 260 N/C
Area of triangle =
=
= 0.0271 m³
electric flux = E. A
= 260 × 0.0271
= 7.046 N m²/C
since, tetrahedron does not enclose any charge so, net flux through tetrahedron is zero.
electric flux through the three side = (electric flux through base)/3
=
electric flux through the three side = 2.35 N m²/C
