Question

please show newt work

(d) Electric charge corresponds to (position, speed, acceleration) of the mass. [12] 13. A piece of wire is bent in the shape shown (two 550 cm horizontal section and a semi circle section with radius 285 cm). Determine the magnetic field (magnitude and direction) at point P, the center of the semicircle. The current i = 19.5 mA. (Hint you need Biot-Savart Law.) If you show your work in an organized and clear manner that I can clearly see that you are working the problem correctly and not just writing from the memory of some problem that was previously worked out, you will get partial credit, depending on how correct you work is.

Answer 1

from Brot- Savart low if a wire is placed and magnetoc field is asked parallet to the wire near end it the = centre will be zero. op Bp = 0 and the at a circle it is B = for fell circle, for Mo I 22 be halt it will B=- Mo I 4R BE 40 x 10 x 19.5 x 10-3 4 x 205 x 10-2 0.05374 xio-8 5.374 X 1070 Tesla B = B =
