The mass of the sun is 1.99×1030kg and its distance to the earth is 1.50×1011m. what is the gravitational force of the sun on the earth?

Explanation:

According to Newton's law of Gravitation, the force exerted between two bodies of masses and  and separated by a distance  is equal to the product of their masses and inversely proportional to the square of the distance:

  (1)

Where:

is the Gravitational Constant and its value is

is the mass of the Sun

is the mass of the Earth

 is the distance between the Sun and the Earth

Substituting the values in (1):

  (2)

Finally:

  This is the gravitational force of the Sun on the Earth.

are their multiple choices ?

explanation:

when it gains or loses electrons
