Question

A sphere of mass 40 kg is attraced by a second sphere of mass 15
kg when their centers are 20 cm apart, with a force of 0 1
milligram weight Calculate the value of gravitational constant

Here,
m1=40 kg,   m2=15 kg,   r=20 cm=0
2 m

Weight, W=0 1 mg   or force, F=9
8×10-6N

Using the expression, G=F×r2m1×m2

We get,
G=9 8×10-6×0 2×0 240×15   =0
392×10-6600=6 6×10-11 Nm2/kg2

A sphere of mass 40 kg is attraced by a second sphere of mass 15 kg when their centers are 20 cm apart, with a force of 0.1 milligram weight. Calculate the value of gravitational constant.
