Question
1. Which one of the following statements is true concerning the strength of the electric field between two oppositely charged parallel plates?
It is the same everywhere between the plated if any edge effect is ignored.
It is a maximum near the negatively charged plate.
It is a maximum near the positively charged plate.
It is a maximum midway between the plates.
It is zero midway between the plates.
2. An electron traveling horizontally to the right enters a region where a uniform electric field is directed downward. What is the direction of the electric force exerted on the electron once it has entered the electric field?
downward
upward
to the left
to the right
the direction of the force depends on the speed of the electron

Explanation / Answer
1. Which one of the following statements is true concerning the strength of the electric field between two oppositely charged parallel plates?
Ans :
It is the same everywhere between the plated if any edge effect is ignored.
Uniform field (The electric field between two closely spaced, oppositely charged parallel plates is constant.)
2. An electron traveling horizontally to the right enters a region where a uniform electric field is directed downward. What is the direction of the electric force exerted on the electron once it has entered the electric field?
Ans : Upward
Because the direction of negative charges in the uniform electric field is opposed to the direction of that field.(the electric field is directed downward)
It is the same everywhere between the plated if any edge effect is ignored.
Uniform field (The electric field between two closely spaced, oppositely charged parallel plates is constant.)
