Answer:
Explanation:
The question: What is the net force exerted by these two charges on a third charge q_3 = 47.0 nC placed between q_1 and q_2 at x_3 = -1.240 mm ?
<u>Your answer may be positive or negative, depending on the direction of the force.</u>
Solution:
The coulomb force is given by the equation
where is the separation between the charges and .
Now, in our case
The separation between charges and is
Therefore, the force between them is
and it is directed in the negative x-direction.
The separation between charges and is
therefore, the force between them is
Therefore the total force on charge is
