Two proton beams are moving in the parallel direction. Which of the following statements are correct. This question has multiple correct options

Q2PhysicsUnit 13: Magnetic Effects of Current and Magnetism

The force between two current carrying wires is due to the force.

Q3PhysicsUnit 13: Magnetic Effects of Current and Magnetism

Two conductors each of length

12 m

lie parallel to each other in air. The centre to centre distance between the two conductors is

15 \times 10^{-2} m

and the current in each conductor is

300 A

. The force in newton tending to pull the conductors together is:

Q4PhysicsUnit 13: Magnetic Effects of Current and Magnetism

Two parallel conductors

P

and

Q

of equal lengths carry currents I and

5 I

respectively in the same direction, then.

Q5PhysicsUnit 13: Magnetic Effects of Current and Magnetism

Two parallel wires carrying currents in the same direction attract each other because of

Q6PhysicsUnit 13: Magnetic Effects of Current and Magnetism

Assertion When two long parallel wires, hanging freely are connected in series to a battery, they come closer to each other. Reason Wires carrying current in opposite direction repel each other.

Q7PhysicsUnit 13: Magnetic Effects of Current and Magnetism

and

i_{2}

respectively. The force experienced by each of the straight wires is

(r

is the distance of their separation)
