Which of the following statements is not correct? a. The weight of a body on Earth is a measure of the gravitational attraction of Earth on that Gravitational force is a scalar quantity because it has magnitude only. The gravitational mass of a body depends on its surroundings and altitude. d Weight and force have both magnitude and direction. Apod 13. Which of the following statements about gravitational force, F, is not correct? The gravitational force between two objects depends on their separation. b. Gravitational force is an attractive force only, it is never repulsive. C. Gravitational forces always exist in pairs of equal magnitude. P. Gravitational force is the strongest of the fundamental forces,Newton's universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, it can be written as GMm F = According to this law, when distance between two masses is reduced by half, the force becomes half compared to original O becomes two times larger compared to original becomes quarter of the original becomes four times larger compared to original
