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`.

A

`5`

B

`8`

C

`7`

D

`10`

Text Solution

Verified by Experts

The correct Answer is:
C
(c) `B=(mu_0I)/(4pi (12x)/5)[cos 53^@+cos37^@]=7((mu_0I)/(48pix))`
`:. K=7`
