An electron with initial velocity vx0 =1.0 *10^4 m/s enters a region of width 1.0 cm where its electrically accelerated. it emerges with velocity vx = 4.0 *10^6
what was its acceleration, assumed constant?
F = ma
v^2 = u^2 + 2as
The Attempt at a Solution
Well I thought I would try this
(v^2 - u^2)/2s =a
but this did not work.
Im guessing I am going to need to find E?
But dont know how to do this with given information.
can someone point me in the direction of the formula needed for the question?
