Answer:
Let's start by understanding what exactly a scientific question is. A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. A good scientific question has certain characteristics. It should have some answers (real answers), should be testable.

Explanation:
Answer:
a) the force goes down, b) The electric force is out of the screen
c) the force is zero
Explanation:
To determine the direction of a magnetic force we use the right hand rule. For a positive charge, the thumb is in the direction of speed, the fingers extended in the direction of the magnetic field, and the palm points in the direction of force. Let's apply this to our case
a) thumb to the right
Fingers spread out
And the force goes down
b) the electric force in the direction of the electric field if the charge is positive
Positive charge
Electric field out of the screen
The electric force is out of the screen
c) charge moving out screen
Magnetic field entered on the screen
Since they are parallel, therefore the force is zero
