Answer:
Explanation:
Let's define positive to be right. The net force on q2 is the
vector sum of the forces from q1 and q3.
The force has a magnitude of and points to the left.
Handling the signs correctly is critical. The negative signs
come from the direction of each of the forces (both to the left),
not from the signs of the charge.
2. Both charges 1 and 3 have 1 close
neighbor and 1 far neighbor. Will
they experience forces of the same
magnitude?
No, because both forces acting on charge 1 are in the same
direction, while the two forces acting on charge 3 are in
opposite directions. Thus, 1 > 3.
Both charges 1 and 2 have two forces acting in the same
direction. Will they experience forces of the same magnitude?
No, because one force acting on charge 1 is the same
magnitude as one acing on charge 2, while the second force
acting on charge 1 is smaller – it comes from a charge farther away
