How Does a TV Use Electric Fields to Control Electron Beams?
A pair of horizontal plates is used to deflect electrons up or down in a television set by placing a potential difference across them. The plates have length 0.04 m. and separation 0.012 m, and the right edge of the plates is 0.50 m from the screen. A potential difference of 200 V is applied...- krosenberg

Electrostatic Potential in Electric Fields
Homework Statement 1. Four charged particles are held fixed at the corners of a square of side s. All the charges have the same magnitude Q, but two are positive and two are negative. In Arrangement 1, shown below, charges of the same sign are at opposite corners. Express your answers to...- krosenberg

How to weigh an object that's heavier than the max. weight of the spring scale
Homework Statement suppose that a spring is used in a spring scale that is limited to a maximum value of 25N, but you would like to weigh an object of mass M that weighs more than 25N. What commonly available equipment, along with the spring scale, can be used to determine the weight of the...- krosenberg
