A segment of a conductor in the shape of circular arc carries a current I and is in a uniform magnetic field region with strength B. It has a radius R, bisected by the y-axis, and subtends an angle 180° + 20 with = 40°; see figure below. The magnitude of the total magnetic force on the arc is most nearly BO 0 (A) 21RB cos 20°. (B) 21RB cos 40.0°. (C) 2√21RB sin 20º. (D) 21RB sin 40.0°. (E) 21RB sin 20°
