Calculate the electric field at the point x meters on the axis of the ring if the total charge on the ring = Q, and there is a point charge of strength q in the center of the ring. Given: Q = 33 nC. q = -18 nC. x = 1.6 m. radius=a=0.6 m.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
