[a]1. Homework Statement [/b]
essentially my "problem statement" is to determine what the mg in the equation T=2π√(I/mgL) is being used to represent
T=2π√(I/mgL)
in a nutshell, i solved a difficult problem in a way that my professor probably didnt intend for the problem to be solved---but i know I can get full credit if i correctly justify my answer. so the equation T=2π√(I/mgL) is for the period of a pendulum.
my question is as follows: is the mg part of the equation being used to
(1) to ONLY to represent Fg ?
or
(2) to represent the total downward forces acting on the pendulum?
for my actual homework assignment, the pendulum is hanging from a sheet of charge, so in that case could i say that the equation for T is T=2π√(I/(Fg+Fe)L) ?
when i do this i get the correct answer but as i said i need to be very specific in my proof/explanation for my answer since I am sure this is an alternative method to solve the problem rather than using gauss' law. this method makes the most sense to me which is why i want to use it.
