A 1.1 kg particle-like object moves in a plane with velocity components vx = 20 m/s and vy = 50 m/s as it passes through the point with (x, y) coordinates of (3.0, -4.0) m.
(a) What is its angular momentum relative to the origin at this moment?
kg · m2/s k hat
(b) What is its angular momentum relative to the point (-2.0, -2.0) m at this same moment?
Explain what is the force felt by the electrons and the nuclei in the rod when the external field described in the problem introduction is applied?
