Question

An electron is released from rest in a uniform electric field which causes it to accelerate toward the top of the screen. What is the direction of the electric field?

• A. To the left
• B. Toward the top of the screen
• C. To the right
• D. Toward the bottom of the screen

Answer 1

The correct option is D Toward the bottom of the screen

The direction of electric field is given by the direction of path followed by a unit positive test charge , when left freely in an electric field . It means a negative charge will go opposite to the electric field , as electron is a negative charge and is moving toward the top of screen therefore the direction of electric field is toward the bottom of screen .
