A particle has a mass of and a charge of C. The particle is moving at a speed of 452 m/s perpendicularly to the uniform electric field when it enters the field, as shown in the diagram. The particle moves 8.62 mm in the direction of the field before it exits it. What is the strength of the electric field?
A positively charged particle with a charge of 2.45 µC and a mass of kg moves perpendicularly to a uniform electric field, as shown in the diagram. Find the speed of the particle at the point where it leaves the field. Answer to two significant figures.
A pair of oppositely charged parallel plates separated from each other by a 10 m distance have a potential difference of 20 V across them due to the uniform electric field between them. A positively charged object is propelled into the field perpendicular to its direction, starting from the positively charged plate and crossing the field completely in the time it takes the object to reach the negatively charged plate, which is 0.64 s. The object is retrieved, and the plates are moved so that they are 5.0 m apart. The object is then propelled into the field, and when it crosses between the plates, it is displaced the same distance perpendicular to the direction of the field as the first time it passed between the plates. How much less time is taken for the object to complete its motion if the plates are 5 m apart?
