Answer:
(A). The magnetic field is zero at 0.8 cm.
(B). The magnetic field is zero at 5.56 cm.
Explanation:
Given that,
Current in first wire I = 6.0 A
Current in second wire = 2.6 A
Distance
Distance
(A). We need to calculate the magnetic field
If the currents are in the same direction
The magnetic field is in both wires
Put the value into the formula
Put the value into the formula
The point where the magnetic field is zero
The magnetic field is zero at 0.8 cm.
(B). We need to calculate the point where the magnetic field zero
If the currents are in the opposite direction
The magnetic field is in both wires
Put the value into the formula
Put the value into the formula
The point where the magnetic field is zero
The magnetic field is zero at 5.56 cm.
Hence, This is the required solution.
