<u>Answer:</u>
The correct answer option is: they are equal and opposite.
<u>Explanation:</u>
A force is a push or a pull which acts upon any object as a result of its interaction with another object where the forces are called action and reaction.
And according to the Newton's third law: for every action, there is an equal and opposite reaction.
For example, if a bat hits a ball with a 1000-N force, the force exerted on the bat will also be equal to 1000 N but in opposite direction.

Answer:
20 m/s
Explanation:
The force experienced by a charged particle in an electric field is given by
where, in this problem:
is the charge of the particle
E is the electric field
The electric field here has components:
So the components of the force experienced by the particle are:
Now we can find the components of the acceleration experienced by the particle, using Newton's second law of motion:
where
m = 4.0 g = 0.004 kg is the mass of the particle
The 3 components of the acceleration are:
Now we can find the components of the velocity of the particle at time t using the suvat equation:
where:
are the initial components of the velocity
Therefore, at t = 2.0 s, we have:
And so, the speed of the particle is the magnitude of the final velocity:
