Answer:
Universal Gravitational Constant
Step-by-step explanation:
Universal Gravitational Constant or G is used in calculating the gravitational force between two objects. The force (F) is given by,

where,
M and m = mass of two objects
r = distance between the centers of the two objects
The value of G with an accuracy of 99% was first calculated by Henry Cavendish in 1798.
The value of
m³kg⁻¹s⁻²
