As we have learned

Spherical Capacitor -

It consist of two concentric spheres of radii a and b (a<b) inner sphere charge +Q while outer sphere is earthed.

- wherein

 

 Using C= n^{1/3}c\Rightarrow c= \frac{C}{n^{1/3}}= \frac{C}{8^{1/3}}= \frac{C}{2}= \frac{1}{2}\mu F 

 


Option 1)

            1/8 \mu F

Option 2)

8 \mu F

Option 3)

1/2 \mu F

Option 4)

1/4 \mu F
