What are the magnitude and direction (left or right) of the current required to remove the tension in the supporting springs? g = 10 m/s2 Select one A.2.5 A, right direction B.0.4 A right direction C. 0.4 A, left direction D. 4.0 A, left direction -27:03 Casper

Answer 1

x x x x x Bi tree Img Vng X X X X X X Page 1 is: Ginen B=0.50T Inwards. hength of Tulive = 50.0cm = 0.5m. and its mass an = 0.01kg. now magnetic force will balance the weight of wire. e il B= mg = i= mg 0.01x 10 dB 0.5 x 0.5 : force direction of -) = 0.4 amp. " By using left-hand rule the current is towards right. so correct option is option ®
