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?
♦ Relevant knowledge
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.
