A uniformly charged solid shpere fo radius `R` has potential `V_(0)` (measured with respect to `oo`) on its surface. For this sphere the equipotentail surfaces with potentials `(3V_(0))/(2) , (5 V_(0))/(4), (3V_(0))/(4)` and `(V_(0))/(4)` have radius `R_(1), R_(2), R_(3)` and `R_(4)` respecatively. Then

A

`R_(1)=0` and `R_(2) gt (R_(4) - R_(3))`

B

`R_(1) ne 0` and `(R_(1)-R_(1)) gt (R_(4)-R_(3))`

C

`R_(1)=0` and `R_(2) lt (R_(4)-R_(3))`

D

`2R lt R_(4)`
