Five point charges ( 1 , 2 , 3 , 4 ) and ( -5 nC ) are located inside a pyramid. The total electric flux through the surface of the pyramid is
Options
- A(180 Nm ^2 C ⁻¹ )
- B(90 Nm ^2 C ⁻¹ )
- C(55 Nm ^2 C ⁻¹ )
- D(5 Nm ^2 C ⁻¹ )
Correct answer
A. (180 Nm ^2 C ⁻¹ )
Step-by-step solution
According to Gauss's law, total electric flux ( through the surface of pyramid = Total charge ₀ ) ( aligned & = q ₀ = ( 1 + 2 + 3 + 4 - 5 ) 10⁻⁹ ₀ & = 5 ₀ 10⁻⁹= 5 4 10⁻⁹ 4 ₀ = 20 10⁻⁹ 4 ₀ & =20 9 10^9 10⁻⁹=180 Nm ^2 C ⁻¹ aligned )
