Homework Statement
The Attempt at a Solution
Honestly I'm completely lost, this is an assignment for my calc 3 class. I tried to do (a) but I think I'm completely off track so any helps appreciated.
r x a=0
|r x a|=0=|r||a|sin(theta)
r cannot be 0 since it's in the denominator
Assuming neither G nor M is 0, a cannot be 0
so theta must be 0 or 180
|r||a|sin(0)=0
|r||a|sin(180)=0
the above is my attempt at (a)
I haven't tried any others yet :(.
