A steady current `I` goes through a wire loop `PQR` having shape of a right angle triangle with `PQ = 3x, PR = 4x and QR = 5x`. If the magnitude of the magnetic field at `P` due to this loop is `k((mu_(0)I)/(48 pi x))`, find the value of `K`.

Text Solution

Verified by Experts

The correct Answer is:
7
`B=(mu_(0)i)/(4pi((12x)/5))(sin 37^(@)+sin 53^(@))`
`B=(mu_(0)i)/(48pix)(5xx(4/5+3/5)) rArr B=7((mu_(0)i)/(48pix)) rArr K=7`
