A long conducting wire made of anti-matter carries a uniform current per unit area. The anti-electrons (each carries charge +1.602 x 10-19 C ) with speed 4.862 m/s (the speed and magnitude of the total current is 745.3 A. The current is caused by uniformly distributed moving direction are the same for all moving anti-electrons). The radius a of the long conducting wire is 0.212 m. 1 cm = 0.01 m 299792458 m/s : €0 = 8.85419 x 10-12 C²/(N m²): Mo = 4 x 10-7N/A² C= √HOEO Keep at least three significant figures (keep two more digits after the first the non-zero digit) for all your answers. = (1) What is the density n of these moving electrons (this density is the number of electrons per unit volume)? (1pt) (2) The direction of the magnetic field B at the point illustrated in the right figure at r= 1.78 cm is 6. What is the direction of the moving anti-electrons? You can express your answer in terms of k, Ŷ. ê (1pt) (3) Find the magnitude of the magnetic field B at r= 1.78 cm (1pt) k A long conducting wire made of anti-matter carries a uniform current per unit area.
