Two 2.0 kg masses are 2.0 m apart on a frictionless table. Each has 1.0 μC of charge.
- What is the magnitude of the electric force on one of the masses?
- What is the initial acceleration of each mass if they are released and allowed to move?
The acceleration is proportional to the mass consequently, the acceleration might differ for two particles. Two charged particles separated by a distance of a finite length exert forces on one another that is proportional to their product of their charges. It is also inversely proportional to the size of distance.
