Question 1:

When a proton has a velocity v = (4i + 8j) x 10 m/s, it experiences a force F = -2 x 10-1$ kN. In a second experiment with the same B field, the particle is moving along the +axis, and under these new conditions it experiences a force along the + axis. What is the magnetic field? K ) TA charge q = -0.3 C has a velocity of 1000000 m/s at 45" to the +x axis in the z plane, with a positive @ and & component. There is a magnetic field of magnitude 0.04 T. a) If B is along the +zaxis, what is the force on the charge? N along the +y axis b) If the force on the charge is 3 x 10 N along +yaxis, what is the direction of B? degrees from the + zaxis in the xz plane.2 B C A rectangular coil has 17 turns and sides of length a = 30 cm and c = 35 cm. The coil is pivoted about the z axis and its plane is at 0 = 35" to a magnetic field B = 0.6i T, as shown in the figure above. If I = 10 A, find: a) the force on each side. F1 =( it j+ k)N it j+ k)N i+ j+ k)N FA it k) N b) What is the magnetic moment of the coil? 1 =( Jitik) A . m c) What is the torque on the coil? T =( it its ) N . m
