1. For a stationary ball of mass m = 0.200 kg hanging from a massless string, draw arrows (click on the “Shapes” tab) showing the forces acting on the ball (lengths can be arbitrary, but get the relative lengths of each force roughly correct). For this case of zero acceleration, use Newton’s 2nd law to find the magnitude of the tension force in the string, in units of Newtons. Since we will be considering motion in the horizontal xy plane,...

A hanging weight, with a mass of m1 = 0.370 kg, is attached by a string to a block with mass m2 = 0.850 kg as shown in the figure below. The string goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As...

1. An object of mass 1.2 kg is attached to a string of 0.83 m. When this object is rotated around a horizontal circle, it completes 15 revolutions in 9.6 seconds. a. What is the period (T) of this motion? b. What is the tangential velocity of the object? c. What is the tension on the string? Hint: The tension on the string is the centripetal force that causes the circular motion.

A small spherical insulator of mass 8.0 × 10-2 kg and charge (left) +0.500 μC is hung by a thin wire of negligible mass. An identical spherical mass with a negative charge of -1.900 μC (right) is held 0.20 m away from the sphere and directly to the right of it, so the wire makes an angle with the vertical (see the drawing). What is the magnitude of tension in the wire? (m g/cosθ = 0.813 N) What is the...
