Assertion : We can not move even a finger without disturbing all the stars.
Reason : Every body in this universe attracts every other body with a force which is unversely proportional to the square of distance between them.

Assertion : We can not move even a finger without disturbing all the stars. Reason : Everybody in this universe attracts every other body with a force which is inversely proportional to the square of distance between them.

Why cannot we move a finger without disturbing all the stars ?

We cannot move finger without disturbing all stars. Why?

According to Newton's law of gravitational, everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and is inversely proportional to the square of the distance between their centres, i.e., F prop (m_(1)m_(2))/(r^(2)) or F = (Gm_(1)m_(2))/(r^(2)) where G is universal gravitational constant = 6.67 xx 10^(-11) Nm^(2) kg^(-2) . (i) What is the value of G on the surface of moon? (ii) How is the gravitational force between two bodies affected when distance between them is halved? (iii) What values of like do you learn from this law?

According to Newton's law of gravitation , everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and the inversely proportional to the square of the distance between their centres, i.e., F prop (m_1m_2)/(r^2) or F=G(m_1m_2)/(r^2) where G is universal gravitational constant =6.67xx10^(-11)N*m^2*kg^(-2) . Read the above passage and answer the following questions : (ii) How is the gravitational force between two bodies affected when distance between them is halved ?

One physics expert has said that 'We cannot move our fingers without disturbing all stars'. Explain the logic behind this statement.
