A small mass M attached to a string slides in a circle (x) on a
frictionless horizontal table, with the force F
providing the necessary tension (see figure). The force is then
increased slowly and then maintained constant when M travels around
in circle (y). The radius of circle (x) is twice the radius of
circle (y).

A 1.6 kg particle moves in a circle of radius 3.1 m. As you look down on the plane of its orbit, the particle is initially moving clockwise. If we call the clockwise direction positive, the particle's angular momentum relative to the center of the circle varies with time according to L(t) = 10 N · m·s - (5.0 N · m)t. (a) Find the magnitude and direction of the torque acting on the particle in N · m. Is...

A wheel of radius a, with its mass M concentrated on the rim, is rolling with velocity v round a circle of radius R(>> a), maintaining a constant inclination alpha to the vertical. If omega is the angular velocity of the wheel about its axis, and Omega (Omega<< omega) is the precessional angular velocity of the axis, what is it's total angular momentum vector? (Using spherical polars and taking the centre of mass of the wheel as origin.)

2. An electron moves in a circle of radius r = 5.66 x 10-11 m with a speed 2.09 x 10 m/s. Treat the circular path as a current loop with a constant current equal to the ratio of the electrons charge magnitude to the period of the motion. If the circle lies in a uniform magnetic field of magnitude B = 6.39 mT, what is the maximum possible magnitude of the torque, T, produced on the loop by the...
