Two concentric shells have radii R and `2R` charges `q_A` and `q_B` and potentials `2V` and `(3/2)V` respectively. Now, shell B is earthed and let charges on them become `q_A'` and `q_B'`. Then,

A

`(q_A)/(q_B)= (1)/(2)`

B

`(|q'_A|)/(|q'_B|)=1`

C

potential of A after earthing becomes `((3)/(2))` V

D

potential difference between A and B after earthing becomes `(v)/(2)`
