A and V 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)`
