Two straight wires are in parallel and carry electrical currents in opposite directions with the same magnitude of LaTeX: 2.02.0LaTeX: AA. The distance between the two wires LaTeX: 5.05.0 LaTeX: mmm m. If one of the wires is infinitely long and the other the wire is LaTeX: 0.30.3 LaTeX: mm long, what is the magnitude of the force between the two wires?

Explanation:

We are given that

Distance between the wires,

1mm=

Length of other wire,l=0.3 m

Length of one wire is infinite.

We have to find the magnitude of force between the two wires.

We know that magnetic force

Where

When the wires carrying equal current in opposite direction then the force between two wires repel to each other.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
