Question

Two persons having mass 50 kg each, are
standing such that their centre of gravity are
1 m apart. Calculate the force of gravitation.
[Ans: 1.67 x 10-7N​

Answer 1

Gravitational force acts on all objects in proportion to their masses. Why then, a ... By applying universal law of gravitation: - F = (G m 1 m2/r2). = (6.67 x 10-11 x 6 × 1024 x 1)/ (6.4 × 106)2.

Answer 2

Answer:

Yes your answer is correct

1.67×10-7N is the correct answer

Explanation:

(Take G=6.67×10

−11 N

m2 kg −2

, mass of earth M=6×10 24 kg, Radius of earth R=6.4×10 6 m)

1.67×10 −7N

When both masses are equal then,

As we know that Gravitational force is given by

F=GM²/R²=6.67×10−11 ×50×50/1×1=1.67 x 10-7N
