The electron, having been held at height h0, is now released from rest. Calculate its speed v when it reaches the top plate.
I found the initial energy to be:
-q_e*E*h_0
and the final energy to be:
1/2*m*v^2+-q_e*E*h_1
And I need to solve for v, so I set the two equal to each other as per the conservation of energy thereom and solve for v, correct?
-q_e*E*h_0 = 1/2*m*v^2+-q_e*E*h_1
My problem is isolating v and cancelling/clearing up variables. My algebra is lagging a bit, admittedly. Thanks for any help.
