  • How to solve this problem- A and B are two conductors carrying a current i in the same direction. x and y are two electron beams moving in the same direction

A and B are two conductors carrying a current i in the same direction. x and y are two electron beams moving in the same direction

  • Option 1)

    There will be repulsion between A and B attraction between x and y


     

  • Option 2)

    There will be attraction between A and B, repulsion between x and y

  • Option 3)

    There will be repulsion between A and B and also x and y

     

  • Option 4)

    There will be attraction between A and B and also x and y

As we learnt in 

force between two parallel current carrying conductors -

F=\frac{\mu }{4\pi } \frac{2I_{1 I_{2}}}{a} l

\frac{F}{l}=\frac{\mu o}{4\pi } \frac{2I_{1 I_{2}}}{a}

- wherein

I1 and I2 current carrying two parallel wires 

a-seperation between two wires 

 

Two parallel current attract each other and hence A and B will attract each other.

e- & e- will repel each other as these two are similar charges.
