Answer:
The same
Step-by-step explanation:
The figure is missing: find it in attachment.
The electrostatic force between two charged particle is:
- Attractive if the two particles have opposite sign charge
- Repulsive if the two particles have same-sign charge
Moreover, a single-point charge produces a radial electric field, whose direction is as follows:
- The field lines point away from a positive charge
- The field lines point towards a negative charge
In the figure attached, we see that:
- The field lines point away from both charges
Therefore, this means that both charges are positive: so, the two charges are the same.
