The analogy is definitely helping. Thank you!
So does that mean this situation is not physically possible?
The electric potential at point P is positive, relative to the potential at infinity which is 0. In that sense, the potential energy should decrease and kinetic energy should increase. But...
Thanks Jbriggs. q is positive. So that means the electron has negative potential energy and will not move, correct? They why does Newton's seconds law and Coulumbs Law predict that it will be repelled by the top negative charge and move away from the system? I feel like there is an...
Homework Statement
Three point charges q,q and -q lie at three corners of an equilateral triangle of side length d with -q at the apex. If an electron is released from rest midway at the base (point P) what is its KE when its reasonably far away?
