The metal plates of a TV tube are parallel and 12 mm apart. The potential difference between them is 12 kV.
a. Find the force on an electron passing between the plates.
b. What acceleration is produced?
Consider a too-small space station that consists of a 2.7m radius rotating sphere. A man standing inside is 1.9m tall and his feet are at 1g. What is the acceleration of his head.
The shell, with radius R and negligible thickness, has net charge - 4.00 q. Find an expression for the electric field strength outside the sphere

A 1250 kg cannon, which fires a 80 kg shell with a speed of 546 m/s relative to the muzzle, is set at an elevation angle of 39° above the horizontal. At what angle with the ground is the shell projected
In the 1950s, an experimental train that had a mass of 2.00 104 kg was powered across a level track by a jet engine that produced a thrust of 5.30 105 N for a distance of 509 m. Find the work done on the train
A mechanic turns a wrench using a force of 30 N at a distance of 18 cm from the rotation axis. What magnitude torque does she apply to the wrench
Two carts with masses of 5.00 kg and 2.64 kg move toward each other on a frictionless track with speeds of 4.86 m/s and 3.46 m/s correspondingly. The carts stick together after colliding head-on. Find the final speed.
