Two point particles, each with charge Q, are placed at positions +- a x.

A) What is the elctric potential anywhere along the y axis?

B) How much energy does it take to move a thrid particle, charge Q, from infinity to a position in order to make an equilateral triangle among the charges? (ie. all edges have length 2a)

Solution Summary

Energy that is estimated in two point particles are given. How much energy it takes to move a third particle is determined.

Solution Preview

A) uppose at position y, the potential due to the charge at a will be k*Q/Sqrt(y*y+a*a),where k=1/(4*pi*(dielectric constant))
Similarly, the potential due to the ...
