SUMMARY
An electron released from rest in a weak electric field of E = -3.00 x 10-10 N/C experiences both electric and gravitational forces. The net force acting on the electron can be calculated using F = qE - mg, where q is the charge of the electron, E is the electric field strength, m is the mass of the electron, and g is the acceleration due to gravity. After traveling a vertical distance of 1.4 µm, the speed of the electron can be determined using the work-energy principle, specifically the equation Work done = F*d = 1/2*m*v2.
