Answer:

Explanation:

The volume of spheres.

27×

​  

πr

=  

3

4

​  

πR  

3

 

where, r and R are the volume of smaller and bigger sphere respectively.

⇒R=3r

Now, initial potential of smaller sphere,

V

​  

 

r

Q

​  

 

∴Q=V  

1

​  

r×4πϵ  

0

​  

 

∴ Charge on 27 spheres, we have

Q  

T

​  

=27×10×r×4πϵ  

0

​  

 

Now, charge on bigger sphere

Q  

B

​  

=V

​  

R×4πϵ  

0

​  

 

Now, Q  

T

​  

=Q  

B

​  

 

⇒270×r×4πϵ  

0

​  

=V

​  

R×4πϵ  

0

​  

 

⇒270r=V

​  

×3r⇒V

​  

=90 V.
