An electron starts from rest 37.0cm from a fixed point charge with Q = -0.105?C .
How fast will the electron be moving when it is very far away?
Ei = ef
k e Q/r = 1/2 mv^2
9.0E9*1.6E-19*0.105E-6/.37 = 0.5*9.11E-31*v^2
v=2.99E7 m/s
Ei = ef
k e Q/r = 1/2 mv^2
9.0E9*1.6E-19*0.105E-6/.27 = 0.5*9.11E-31*v^2
v=3.51E7 m/s

A. What is the potential a distance of 8.5 mm from a point charge of 7.6 uC? B. How much would would it take to move a second charge of 4.9 uC from infinity to that a point that distance from the first charge? (this is the potential energy now stored in the system) C. If you release the send charge, it will move away from the first. How much kinetic energy will it have once it is infinitely far...
