Aparticle with a mass of 2.00×10−4 kg carries a negative charge of - 3.80×10−8 c . the particle is given an initial horizontal velocity that is due north and has a magnitude of 4.21×104 m/s . a) what is the magnitude of the minimum magnetic field that will keep the particle moving in the earth's gravitational field in the same horizontal, northward direction?
b) what is the direction of the minimum magnetic field? (west, east, north, south)

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
