Answer:
The electric field generated by a point charge is given by:
where
is the Coulomb's constant
Q is the charge
r is the distance from the charge
We want to know the net electric field at the midpoint between the two charges, so at a distance of r=5.0 cm=0.05 m from each of them.
Let's calculate first the electric field generated by the positive charge at that point:
where the positive sign means its direction is away from the charge.
while the electric field generated by the negative charge is:
where the negative sign means its direction is toward the charge.
If we assume that the positive charge is on the left and the negative charge is on the right, we see that E1 is directed to the right, and E2 is directed to the right as well. This means that the net electric field at the midpoint between the two charges is just the sum of the two fields:

Step-by-step explanation:
Answer:
The Sum is 49/12 (improper), or 4 1/12 (mixed).
The Difference of these 2 fractions would be 2 1/3 - 1 3/4 instead of adding them. The answer is 7/12.
Step-by-step explanation:
I did it by converting the mixed fractions into improper fractions, then making the denominators the same, and adding them together.

Answer:
2.24
Step-by-step explanation:
The absolute value sign means that any negative number inside turns positive. Its easier to "see" this by thinking of distances. Distances can never be negative, so when you calculate them, in your head you just remove the negative sign. That's what this absolute value sign does.
