1) push down on the end of the lever, and 2) 3/4 of the way from the fulcrum
Answer:
v = 1.15*10^{7} m/s
Explanation:
given data:
charge/ unit area
plate seperation = 1.69*10^{-2} m
we know that
electric field btwn the plates is
force acting on charge is F = q E
Work done by charge q id
this work done is converted into kinectic enerrgy

solving for v



v = 1.15*10^{7} m/s
The answer is a tell me if I am wrong.
