Question

A sphere of mass 40 kg is attracted by second sphere of mass 60 kg with a force equal to 4 mgf. if g=6x 10-11 nm2/kg2, then calculate the distance between them. assume g = 10 m/s2.

Answer 1

Force = 4 mgf = 0.039 N
M1 = 40 kg
M2 = 60 kg
G = 6×10-¹¹ Nm²/kg²
Let distance be d

F = G×M1×M2/d²
0.039 = 6×10-¹¹×40×60/d²
d²= 14400×10-¹¹/0.039
d²= 3.69×10^-6 m²
d= 1.92×10-³ m

hope this helps :-)
