STJ (singkat, tepat, jelas) dan benar
catatan
Jika terdapat 2 vektor sama besar, misal x dan saling tegak lurus, maka resultannya
R =
Ok ?
diketahui : massa benda penyebab grafitasi = m
massa benda A = 2.m
massa benda B = 2m
massa benga C = 4 m
massa benda D = 4 m
rA = rB = rC = rD = a
ditanta R dan arah
gx.A = gA .cos
= G .
=
gx.B = gB .cos
= gB . 0
= 0
gx.C = gC .cos
= G.

gx.D = gB .cos
= gB . 0
= 0
∑gx = -

gy.A = gA .sin
= gA . 0

gy.B = g.B .sin
= G.
=
gy.C = g.C .sin
= g.C . 0
= 0
gy.D = gD .sin
= G .
