An electron is released from rest 2.0 cm from an infinite charged plane. It accelerates toward the plane and collides with a speed of 1*107 m/s
What is the surface charge density of the plane?
The Attempt at a Solution
therefore a∆t = 1*107 m/s
calculating the time ∆t requires knowledge of either v0 or a, v0 is zero, so one cannot calculate it using v0, so the other option is to use a, which is unknown also
How would I go about this?
Once I have a, i can find E using the formula a=(qE)/m
