For a capacitor, distance between the plates =d, p.d between the plates =V,k=1, area of each plate =A and electric field between the plates =E. For another capacitor distance between plates =d, p.d between plates =V,k=2, area of each plate =2A and electric field between the plates =E1. Relation between E and E1 is:
E1=E/4
E1=E/2
E1=E
E1=4E
A
E1=E/4
B
E1=4E
C
E1=E/2
D
E1=E

E=Vd
where, V− potential between plates
and, d− distance between plates
so, no change in V and d
