A beam with negligible mass is balanced by two external forces at R1 = 1.5 meters and R2 = 6.5 meters. If F1 = 10 N, what is F2.(adsbygoogle = window.adsbygoogle || []).push({});

i got this:

(10)(1.5) + F2(6.5) = 0

so F2 = 2.31 N

but the second part i dont get:

If the beam actually has a weight of 3 N, what would F2 be now???
