Answer:
b
Explanation:
they both have a neutral charge so they couldn't be positive or negative since that wouldn't come from anywhere
They create energy ……………….
Answer:
The extension of the second wire is 
Explanation:
From the question we are told that
The length of the wire is 
The elongation of the wire is 
The tension is 
The length of the second wire is 
Generally the Young's modulus(Y) of this material is

Where 
Where A is the area which is evaluated as

and 
So

Since the wire are of the same material Young's modulus(Y) is constant
So we have


Now the ration between the first and the second wire is

Since tension , radius are constant
We have

substituting values
