A long, thin rod (length = 3.0 m) lies along the x axis, with its midpoint at the origin. In a vacuum, a +9.0C point charge is fixed to one end of the rod, and a -9.0HC point charge is fixed to the other end. Everywhere in the x, y plane there is a constant external electric field (magnitude 4.0 x 103 N/C) that is perpendicular to the rod. With respect to the z axis, find the magnitude of the...

A uniform thin rod of mass m and length 5b is suspended from the ceiling by a single string of length 2b attached to one end (this end of the rod is called P1). Thus in equilibrium the string and rod hang straight down and the lower end of the rod is a distance 7b from the ceiling (this end of the rod is called P2). The motion is constrained to be in a fixed vertical plane, so we have...
