A sphere `S_1 ` of radius r enclose a total charge Q. If there is another concentric sphere ` S_2` of radius `r_2 (gtr_1) ` and there be no additioanl charges between `S_1 and S_2` find the ratio of electric flux through `S_1 and S_2`

Text Solution

Verified by Experts

`(phi_2)/(phi_1) =(q_1//in_0)/(q_2//in_0) =(q_1)/(q_2) =(Q)/(Q)= 1.` [since charge within both spheres is same =Q ]
