A point charges of `2.0 muC ` is at the centre of a cubic Gaussian surface `9.0 cm ` on edge . What is the net electric flux through the surface?

Text Solution

Verified by Experts

` because ` Charges inside the cubic Gaussian surface `q= 20 muC =2.0 xx 10^(6) C `
` therefore ` Total electric flux through the surface of cube
` phi _in =(q)/(in_0) =(2.0xx10^(-6))/(8.85xx10^(-12)) =2.2 xx 10^(5) Nm ^(2) C^(-1) `
