A parabolic wire as shown in the figure is located in x-y plane and carries a current l=10 amp. A unifrom magnetic field of intensity 2sqrt(2T), making an angle of 45^(@) with x-axis exists throughout the plane. If the coordinates of end point 'P' of wire are (2m, 1.5 m) then the total force acting on the wire is:
