Two conducting parallel plates 5.0 × 10−3 meter apart are charged with a 12-volt potential

difference. An electron is located midway between the plates. The magnitude of the electrostatic

force on the electron is 3.8 × 10−16 newton.

Calculate the magnitude of the electric field strength between the plates, in newtons per coulomb

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue
