Homework Statement
In the figure below, a charged particle (either an electron or a proton) is moving rightward between two parallel charged plates separated by distance d = 2.30 mm. The particle is speeding up from an initial speed of 3640 km/s at the left plate.
Homework Equations
The equation that I was given to use (The one my professor worked out on the board) is:
W(cons)=-ΔV=ΔK=-(-e)(ΔV)=1/2 m(particle)(Vf2-Vi2)
The first part of the problem was to find out if the particle was an electron or a proton. It is an electron.
The Attempt at a Solution
1/2 (9.1*10-31)*36402= 6.02*10-24
This was not correct.
