Answer:
Explanation:
It is said that a sphere of mass 40 kg is attracted by a second sphere of mass 15kg, when their centers are 20cm apart, with a force of 0.1 milligram weight. ... ⇒G=F(r)2m1m2=98×10−8×0.2×0.240×15=6.53×10−11 . Therefore the value of gravitational constant G here is 6.53×10−11Nm2kg−2.
