A METAL SURFACE HAS A POSITIVE CHARGE OF 109 C HOW MANY ELECTRONS WOULD HAVE BEEN REMOVED...
The elementary charge is 1.6x10^19 . Thus to find the number of electrons removed from the surface divide the total charge by the elementary charge i.e. 10^9/(1.6x10^19) by using the formula q=ne...

since potential difference is directly proportional to the charges then V proportional to Q1*Q2
V1/V2 = Q1*Q2/Q`1*Q`2
V1/V2 = Q*2Q/2Q*2Q
On simpliyfing V1/V2 = 2/4 V1/V2 = 1/2
2V1=V2
