Given:

  • If the charge of +7 mC is placed at the centre of two concentric spheres with the radius 2.0cm and 4.0cm respectively

Need to find :

  • Ratio of the flux through them will be ?

Calculation:

Gauss law :- ø = q/Eₒ

1. For small sphere:- ø1 = q/Eₒ

2. For large sphere :- ø2 = q/Eₒ

=> ø1/ø2 = (q/Eₒ)/(q/Eₒ)

=> ø1/ø2 = 1/1

Ratio of flux is 1:1
