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 magnitude of the magnetic field at P due to this loop is `k((mu_0I)/(48pix)),` find the value of k.
8
7
6
2
net magnetic field comes out to be mu*i*2/12*pi*x
so answer should be 8
how 7?
