Question

Is it possible for the charges to be at stable equilibrium in a purely electrostatic field ?

Answer 1

what do you think ?

Answer 2

nope @Mashy

Answer 3

i think yes

Answer 4

centrifugal forces aren't real forces so they can't do work.It is type of pseudo force in the frame of the body in circular motion.It is just a tool to solve problem in that frame (non inertia).

Answer 5

What are u trying to tell @Mashy .I can't understand the diagram

Answer 6

thanks

Answer 7

thats the direction of E field..
in this configuration, don't u think the charges can be in equilibrium ?

the positive charge experiences a force towards the right due to the E field, and left due to the -ve charge.. so its possible for certain particular vaues of E and q, and the distance, these forces can cancel right?
