Question

An electron is moving horizontally in a laboratory when a uniform electric field is suddenly turned on. This field points vertically upward. Which of the paths shown will the electron follow, assuming that gravity can be neglected?

Answer 1

Step-by-step explanation:

We know that electron always tends to travel in the direction opposite the direction of electric field ( force in directed opposite to the field on electron).

So, since the field points vertically upward , it force the electron move downward. So, the electron will be accelerated in downward in the right direction.
