Question

PHYSICS.... NOT CHEMISTRY

If the gravitational force between the two objects is 2.0×10 ^-7 N and the value of gravitational constant, G= 6.67×10 ^-11 n m² kg¯², what is the value of D?​

Answer 1

F=Gm1m2/D*2

or,2.0×10^-7 = (6.67×10^-11 ×75×90)/D^2

or,2.0×10^-7 = (45022.5×10^-11)/D^2

or,D^2=22511.25×10^-4

D=1.5003m
