Gm1.m2/r2 F = G . M1 . M2 / r2 3,34 x 10^-9 = G x 2 x 4 / r2 3,34 x 10^-9 = 8 x 6,67 x 10^-11 / r2 3,34 x 10^-9 = 53,36 x 10 ^-11 /r2 R2 = 3,34 x 10^-9 / 53,36 x 10^-11 R2 = 0,06 x 10^2 R2 = 6 R = 3 akar 2

Dik m1 = 2 kg m2 = 4 kg F = 3,34 x 10^-9 N G = 6,673 x 10^-11 Nm^2/kg^-2 r = ?
F = G m1.m2 / r^2 r^2 = G.m1.m2 / F r^2 = 6,673 x 10^-11 . 2 .4 / 3,34 x 10^-9 r^2 = 53.384 x 10^-11 / 3,34 x 10^-9 r^2 = 15,983 x 10^-2 r = √15,983 x 10^-2 r = 0,399 atau 3,99 x 10^-1 r = 0,40 atau 4,0 x 10^-1
F = G . M1 . M2 / r2
3,34 x 10^-9 = G x 2 x 4 / r2
3,34 x 10^-9 = 8 x 6,67 x 10^-11 / r2
3,34 x 10^-9 = 53,36 x 10 ^-11 /r2
R2 = 3,34 x 10^-9 / 53,36 x 10^-11
R2 = 0,06 x 10^2
R2 = 6
R = 3 akar 2
m1 = 2 kg
m2 = 4 kg
F = 3,34 x 10^-9 N
G = 6,673 x 10^-11 Nm^2/kg^-2
r = ?
F = G m1.m2 / r^2
r^2 = G.m1.m2 / F
r^2 = 6,673 x 10^-11 . 2 .4 / 3,34 x 10^-9
r^2 = 53.384 x 10^-11 / 3,34 x 10^-9
r^2 = 15,983 x 10^-2
r = √15,983 x 10^-2
r = 0,399 atau 3,99 x 10^-1
r = 0,40 atau 4,0 x 10^-1
semoga membantu ^_^
