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
