Physics help! Fill in the blanks:

The strength of the gravitational field varies _______ with the _______ of the _______ from the centre of the earth and _______ with the mass of the body producing the _______.

I got the first three: inversely, square, and distance. I really can't figure out the last two. :( Someone please help!

Newton's Law of Universal Gravitation

Fg = G (m1*m2)/(d^2)

The force of gravity between two objects is inversely related to the square of the distance between their center of masses and is directly related to the product of the mass of each object.

Usually, one mass is the mass of the planet (earth) let's say m1 and the other mass is another object (test object or body or you) m2.

When referring to a gravitational field you are referring to the magnitude of G(m1)/(d^2) at different locations d above the center of the earth.

To answer your question, since the statement starts with the "field" concept,

directly    and     field ( or gravitational field)
