III. Procedure: A charged body having charge Q = 0.002 C, mass M= 0.004 Kg, was initially held at rest at a voltage line located at height=H=D= 2m. Varying amounts of voltages were applied at the voltage line. The time the charged body took to fall to the zero-voltage level of the ground were measured using a digital smart timer. Attracted by the electrical force, the charge falls to the zero-voltage ground in the indicated times. Since the electrical forces...

A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m.
A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 25° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk=0.18. In the initial position, where the spring is compressed by a distance of d = 0.12 m, the mass is at its lowest...
