Question

Find the gravitational force between two persons
seated 0.5m apart and having masses of 40kg and 45kg?​

Answer 1

Answer:

4.8×10^-15

Explanation:

Given:

mass of body A = 40kg

mass of body B = 45 kg

Distance between them = 0.5 m

so, F = GMm

-------------

d^2

F = 6.67×10^-11×40×45

---------------------------

(0.5)^2

= 6.67×10^-11×1800

-------------------------

0.25

= 12006×10^-11

-------------------

0.25

= 48024 ×10^-11

~4.8 × 10^-15
