In the force calculated, you are supposed to use the arc length instead of the perpendicular distance. that is r.θ = {(20).(50).(π/180)}=17.46; hence, force = 70070/17.46 = 4013.17 N and not 4574 N
Anyway, I was thinking of total energy of universe, and somehow came across this video(sigh), you guys got back my schooling memories, thank you.
unrelated to the video: very nice sideburns

Small correction folks:

good shit..you made it sound a lot easier rather than when i was reading it through my university physics book

Awsome, this understand these equations when different angles are used. Thanks Fez and guy I don't know the name of.
