answer all questions please
A wire formed in the shape of a right triangle with base Lab 33 cm and height Lbc 77 cm carries current I- 401 mA as shown in Position 1. The wire is located in a region containing a constant magnetic feld B 0.9T aligned with the positive z-axis. What is Facx, the x-component of the force on the segment of the wire that connects points a and c in Position 1? What is Fac.y the y-component of the force on the segment of the wire that connects points a and c in Position 1? The wire is now rotated 180 about the y-axis to Position 2, as shown. What is ??12, the change in potential energy of the wire? Note that AU12 is a signed number. AU12 is positive if the potential energy in Position 2 is higher than the potential energy in Position o"The wire is now rotated back 90° about the y-axis towards position 1. If the wire is released from this position, how would it move? "The wire is now returned to Position 1 and then rotated 180 about the x-axis to Position 3, as shown. What is AU13, the change in potential energy of the wire? If the potential energy increases in going from Position 1 to Position 3, the change in potential energy is positive. PeationExplanation / Answer
a) Fac,x = -ILBCB
Fac,x = - 0.401 * 0.77 * 0.9
Fac,x = - 0.27789 N
b) Fac,y = -ILabB
Fac,x = -0.401 * 0.33 * 0.9
Fac,x = - 0.119097 N
C) Change in U = ILab Ibc B
change in U = 0.091704 J
d) The wire will move towards position 1 Option 1 is correct. A torque in negative direction will cause the wire to move to position 1.
e) same as part (c)
