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 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...
