The discussion revolves around the force experienced by an electron moving through electric and magnetic fields, specifically with given values for velocity, electric field, and magnetic field. The context includes the application of the Lorentz force equation.
The discussion is ongoing, with participants providing feedback on each other's calculations and notation. There is acknowledgment of potential errors in the application of the right-hand rule and the need for clearer expression of vector products. The original poster is seeking clarification on the differences between their results and those from masteringphysics.com.
Participants note that the original calculations may have involved errors in the right-hand rule application and that the results differ from those expected according to an external source. There is a focus on ensuring clarity in future calculations and expressions.

An electron travels with v= 5.90(10)^{6} i through a point in space where E=<2.30 (10)^{5} i, -2.30(10)^{5} j> and B = <-0.200 k>
Homework Equations
F=q(E+(v x B)
The Attempt at a Solution
I did q of the electron equals 1.6(10)^-19 the with v x B = -.2k (5.9)10^6 i= -1.18(10)^6 j getting 1.6(10)^-19<2.3(10)^5 i, -2.3(10)^5 j + -1.18(10)^6 j> = <3.68(10)^-13 i , -1.41(10)^-13>
shadowtracker said:Alright i will take that into account on future questions...and i guess i should have clarified that masteringphysics.com said i was incorrect and that the correct answer was <-3.68E-14, -1.52E-13> so I'm wondering what they did to get there.
