Your answer is partly correct. Try again The figure below shows across section of along thin bbon of with w- 5.21 m that is carrying a uniformly distributed to rent - 4 ribbon at a distance - 2.45 cm from its edge Cent: Imagine the ribbon as being constructed from many long, thin parallel wires.) to page Calculate the magnitude of the m o st in the game of the Use correct number of significant dit the rolerance is

Answer 1

– 5.21 x 10-2m. width of ribbon, W =521cm Distance of pont p-from the edge of ribbon is 0 d=2.48cm Ribbon is constructed from a w many long, thin, paraulel wires, total current carried by ribbon - 4.334A 1:4.33x10-6A Current per unit length ,k={. 4.33x10-6A 5.21x10-2 m K = 8.31x10-5 Alm Now magnetic field, b = lohkar. Kdr dll or 8 = look f or 10 = 45 x 10-7 Hlm or co, B = 4t7 X10 -* *8. 31x10-s ' ln(dtw). or, B = 5.22x10 " x ln (2.48 +5.21) B = 5.91 x 10-11 T Hans
