Suppose that Earth and the Moon initially have zero charge. Then $1000 \mathrm{kg}$ of electrons are transferred from Earth to the Moon. Determine the radius of a stable moon orbit when both the electrical and gravitational forces of attraction are exerted on the Moon and it completes one rotation about Earth in 27.5 days.

(a.) Find the velocity and acceleration vectors for the particle and find its speed. (b.) Find the Cartesian equation for the particle's trajectory. (c.) Find the curvature $\kappa$ and the tangential and normal components of acceleration for the particle's motion.

Under no-load conditions, a certain motor operates at 1200 rpm with an armature current of 0.5 A and a terminal voltage of 480 V. The armature resistance is $2 \ \Omega .$ Determine the speed and speed regulation if a load demanding a torque of 50 Nm is connected to the motor. Assume that the losses consist solely of heating of $R_A$ and frictional loss torque that is independent of speed.
