Answer:
B. Universal Gravitational Law
Explanation:
As we know that Kepler gives three laws regarding the planetary motion of all planets around the sun
All his laws are derived from the basic Theory of law of attraction by gravitation.
Universal law of attraction given by Sir Issac Newton says that if two masses are placed at some distance from each other then the net force between two masses is given as
[tex]F = \frac{Gm_1 m_2}{r^2}[/tex]
here we know that
[tex]m_1, m_2[/tex] = masses of two objects
[tex]r [/tex] = distance between two objects
