A metal wire is bent in the shape of right angle triangle with sides 3 cm, 4 cm, 5 cm is carrying a current of 1 A. The wire loop is in uniform magnetic field 0.5 T whose direction is parallel to the current in the 5 cm side of the loop. The magnitude of magnetic force on the side 3 cm side will be \(\frac{x}{500}\) N. The value of x is
