Question

The force of attraction between two unit masses separated by unit distance is known as

Answer 1

Answer:

universal gravitational constant

Answer 2

G (Universal Gravitation Constant)

We know,

$F = G \frac{M \times m}{d^2}$

[where, (F) is the force of attraction, (M) and (m) greater and smaller mass respectively and (d) is the distance between them.]

Given that,

M = m = 1 unit

d = 1 unit

Putting the values:-

$F = G \frac{M \times m}{d^2}$

$\implies F = G \frac{1 \times 1}{1^2}$

$\implies F = G$

More about "G" in gravitational:-

• "G" is the constant in the relation between the equation,

$F \propto \frac{Mm}{d^2}$.

• The acceptable value of "G" is $6.673 \times {10}^{-11} N m^2/kg^2$.
• The credit for finding the value of "G" goes to Herny Cavendish who used a sensitive balance to find it's value.
• It is independent of the product of masses and distance between them in fields of gravitation.
