A and B are semi - spherical surfaces of radius `r_(1)and r_(2) (r_(1) lt r_(2)) with E_(1) and E_(2)` as the electric fields a the their surfaces. Charge `q_(0)` is placed as shown. What is the condition which may be statisfied ?

A

`phi_(1)/phi_(2)=1`

B

`r_(1)^(2)r_(1)^(2)=E_(1)E_(2)`

C

`(r_(1))/(sqrtE_(2))= (r_(2))/(sqrtE_(2))`

D

`r_(1)sqrtE_(2)=r_(2)sqrtE_(1)`
