Question

Which of two factors influence the weight of an object due to gravitational pull?

A) the mass and radius of the planet
B) the shape and radius of the planet
C) the rotation and mass of the planet
D) the composition and rotation of the planet

Answer 1

Answer is A, the mass and radius of the planet.

The law of universal gravitation states that gravitational force (weight) is equal to G(m1+m2)/r, and G is a constant number. m is mass and r is radius, so the answer is A.

Answer 2

Answer is: A) the mass and radius of the planet.

Gravity as a force which causes any two bodies to be attracted to each other.

The gravitational effect increases as the size of an object increases. Earth s surrounded by its own gravitational field.

The weight of an object is the amount of force acting on the object due to gravity.

SI unit for weight is newton (N).
