In a region of space having a spherical symmetic distribution of charge , the electric flux enclosed by a concentric spherical Gaussion surface, varies with radius
`r" as "phi={(phi_(0)r^(2))/R^(3), r le R
phi_(0)`, `ltR` where R and `phi_(0)` are the constants.
A. `E=(phi_(0))/(4pir^(2))`,for `rleR`
B. `E=(phi_(0))/(4pir^(2))`,for `rgtR`
C. `E=(phi_(0)r)/(4pir^(2))`,for ` rleR`
D. `E=(phi_(0)r)/(4pir^(2))`,for `rgtR`
