Homework Statement
An electron is released from rest in a uniform electric field. The electron accelerates vertically upward, traveling 4.50 m in the first 3.00\;\mu{\rm s} after it is released.
What is the magnitude of the electric field?
Homework Equations
F = 1/4*pi*e_o * |q| / r^2 for single point charge
e_o = 8.85 * 10^-12
Mass of electron = 9.109 * 10 ^-31
The Attempt at a Solution
1/(4*pi*8.85 * 10^-12) * ( |9.109 * 10 ^-31| / (4.50)^2 )
The online system said the solution was incorrect.
