two charged particles (charge q1=-10, q2=10) of equal masses(m1=m2=1mg) are held fixed a distance r=1 cm apart. what is the electric potential energy of particle 1? Particle 1 is released and accelerates towards particle 2(which remains fixed). What is the speed of particle 1 when it is 0.5cm from particle 2?.

Hi shezil,

I have a rule here: You show us how you started, and we help you with where you got stuck. This problem is not too bad. Give it a shot, and show us what you come up with, OK?

Thanks,
