Question

Find out the force between the wires (50 cm long and 1 cm apart) used to connect the battery of a car to the motor?

Answer 1

Answer:

Current in both wires, I = 300 A

Distance between the wires,

r = 1.5 cm = 0.015 m

Length of the two wires, l = 70 cm = 0.7 m

Since the direction of the current in the wires is opposite, a repulsive force exists between them.

Answer 2

Answer:

The correct answer of this question is  the current in the wires is in the opposite direction, a repulsive force exists between them.

Explanation:

Given -  The force between the wires used to connect the battery of a car to the motor .

To Find - Write down the force between the wires used to connect the battery of a car to the motor .

According to the question,

Current in both wires is I = 300 A

Distance between the wires is - r = 1.5 cm = 0.015 m

Length of the two wires is -  l = 70 cm = 0.7 m

So, that is why  the current in the wires is in the opposite direction, a repulsive force exists between them.
