Answer #1

(A) The force between them will be equal in magnitude but opposite in direction as per Newton's third law.

(B) We can add vector geometrically and algebraically In the geometric process, the tail of any second vector will be kept on the head of the first vector. Then joining the head of second with the tail of first vector will give the resultant vector. The first and second vector can be chosen arbitrarily as the order does not matter.

In the algebraic process, vectors must be represented the Cartesian form. Now the similar component will be added separately, For example, consider two vectors in cartesian form.

then their sum will be

M3: Gravity In the Newtonian model for gravity, gravity is a force between two masses, dependent on the mass of the objects and the square of the distance between the objects’ center of mass. The closer the masses are to each other, the stronger gravity is and the farther they are the weaker it is. Gravity is most commonly understood as the force that makes things fall. Your goal is to understand how the distance an object falls is related...
