Question

what is the mass of a object which is attracted by another mass of 1 kg by a force of 6.67x10-¹¹N if distance between them is 1 m.

2 kg

1 kg

5 kg

4 kg​

Answer 1

Answer:

According to newton's Gravitational Law

=0.66

or r=0.8125 metre =81.25cm=80cm

Answer 2

Answer:

1kg is the answer

Explanation:

According to newton's Gravitational Law

Fg=r2GM1M2 here Fg=10−10 Newton,

m1=m2=1kg,

G=6.6×10−11

So r2=FgGM1M2=10−106.6×10−11×1×1=0.66

or r=0.8125 metre =81.25cm=80cm
