Using the density equation and clearing mass:
The earth is so round that we can run around it in five million days
If they are connected exactly as shown, nothing can happen.
Answer:
The current in the second wire is 4.4 A.
Explanation:
Given that,
Distance =7.0 cm
Current in first wire = 2.0 A
The magnetic field strength is zero at distance of 2.2 cm from the first wire.
We need to calculate the current in the second wire
Using formula of magnetic field




Here, 

Put the value into the formula


Hence, The current in the second wire is 4.4 A.
