What is the vector force exerted by Particle B on Particle A?

Click For Summary
SUMMARY

The discussion centers on calculating the vector force exerted by charged particle B on charged particle A, given that particle A exerts a force of 2.62 microcoulombs on particle B at a distance of 13.7 mm. As particle B moves to a distance of 17.7 mm, the force can be determined using Coulomb's Law. The correct units for force are Newtons, not microcoulombs, which are units of charge. The participants clarify the need to apply the appropriate formula relating electric force to charge and distance.

PREREQUISITES
  • Coulomb's Law for electric force calculation
  • Understanding of electric charge units (coulombs)
  • Basic knowledge of vector forces
  • Familiarity with Newton's laws of motion
NEXT STEPS

Homework Statement


-A charged particle A exerts a force of 2.62 micro coulombs to the right on charged particle B when the particles are 13.7 mm apart. Particle B moves straight away from A to make the distance between them 17.7 mm. What vector force does it then exert on A?


Homework Equations


This is what I am trying to figure out. I'm sort of new to this whole electromagnetism thing.


The Attempt at a Solution

 
Physics news on Phys.org
"A charged particle A exerts a force of 2.62 micro coulombs..."

The units of force are Newtons (typo)?; coulombs are units of charge.

To work thos probelm, use the equation that relates the electric force to charge and charge separation.
 
yeah that was a typo thanks
