8. Electron travelling though two horizontal plates In the diagram P1 and P2 are two parallel horizontal plates that are 12.7 mm apart in a vacuum and have a potential
difference of 169 volts maintained between them, the upper plate being positive. Also, there is a horizontal magnetic field
of 0.033 T as shown.

A horizontal beam of electrons is directed between the plates so that it is moving at right angles to the magnetic field as
shown.
The magnitude of the electric field between the plates, to two significant figures, is:

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

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
