SOLUTION: An electron of mass 9.1E-31 kg is released from rest at a distance of 3.3 E-10 m from a fixed electron. The force on the movable electron is given by the function F = 2.3E-28/r^2,

Question 1056863: An electron of mass 9.1E-31 kg is released from rest at a distance of 3.3 E-10 m from a fixed electron. The force on the movable electron is given by the function F = 2.3E-28/r^2, where r is the distance between the electrons. Find the maximum velocity (in meters/second) of the moving electron after release.

F = 2.3E-28 / ((3.3E-10)^2) = 0.2112E-72
:
0.2112E-72 = (mv^2) / 2
:
mv^2 = 0.4224E-72
:
v^2 = 0.4224E-72 / 9.1E-31 = 0.0464E-41
:
v = square root(0.0464E-41) = approximately 0.6812E-6 m/sec
