A magnetic field of `0.25` T is acting in a region from west to east. A wire PQ is bent and is placed in the magnetic field as shown in figure.

If a current of 5 A flows through the wire, then calculate the magnitude of magnetic force acting on the wire.

Explanation

The magnetic force on the segment PX will be given by
Here, `theta = 0^(@) ` as PX is along the direction of `vecB`.
` :. " " F = 0 `
Similarly, no force will act on the segment YQ. Now, force on the segment XY will be given by
` F = IlB sin (180^(@) " " 120)`
Here , ` I = 5 A, l = 10 cm = 0.1 m`
` = 0.125 xx 0.86`
` = 0.1075` N
