Assume E = yax V/m at a certain instant of time, and compute the work needed to move a 3-C charge from (1,3,5) to (2,0,3) all along the straight-line segments joining:
a) (1,3,5) to (2,3,5) to (2,0,5) to (2,0,3)
b) (1,3,5) to (1,3,3) to (1,0,3) to (2,0,3)
A person carries a long pole of mass 12 kg held at the angle of 60 degrees from horizontal. Determine the magnitude of the torque on the pole due to gravity?
