Gravitational Force: Examining Effects of Distance on Charge

Click For Summary
SUMMARY

The discussion centers on the relationship between electrostatic and gravitational forces acting on two positively charged objects. It concludes that if the electrostatic force equals the gravitational force, the objects will remain in equilibrium at that specific distance. However, due to the significantly stronger nature of electrostatic force—approximately a trillion times greater than gravitational force—any slight disturbance will result in the objects being propelled apart violently.

PREREQUISITES

Homework Statement



What would happen if the size of the electrostatic force acting between two positively charged objects was exactly the same as that of the gravitational force acting between them? What would happen if they were moved closer together or further apart?

You probably mean strength of force. In that case, the 2 forces will cancel each other out at that distance between them and they will stay in equilibrium. However, as electrostatic force is much stronger (in term of trillion times or something) than gravitational force, any disturbance would cause them to fly violently apart.
