Answer:
Explanation:
Since current is flowing in the same direction in both the wires , they will attract each other .
Magnetic field due to first wire on second wire
B = (Ī¼ā / 4Ļ) x 2I / d Ā , I is current on first wire and d is distance of second wire
Force on length L on second wire
F = B I L , B is magnetic field , I is current in second wire and L is length of second wire .
force per unit length of second wire
F/L = B I
= (Ī¼ā / 4Ļ) x 2I / d X I
= 10ā»ā· x 2 x IĀ² / d
The same force will apply on first wire due to second wire as action and reaction forces are equal and opposite.
