Another PHY2 ? ( Thank you Jared for the last help!)?

Question

Determine the magnitude and direction of the force between two parallel wires 35m long and 6.0 cm apart, each carrying 25 A in the same direction

Thanks for your help in advance guys! I am helping my niece with some homework, and I havent taken physics in FOREVER!!!

Answer 1

You would probably get quicker responses posting in Physics for physics questions.

F = μ0 I1 I2 L / (2π r)
= (4π × 10^-7) (25) (25) (35) / (2π (0.060))
= 0.073N inwards (i.e. towards each other).
