Question

d2 9) According to theory of Universal Gravity, every object in the universe attracts every other object with the definite force. This force is directly proportional to the product of the masses of the two objects and is inversely proportional to the square of the distance between them. Mathematically, the gravitational force of attraction between two is given by m1m2 F=G Where, G is the constant of proportionality and is called the universal gravitational constant. If the two objects are spherical, the direction of the force is always along the line joining the centers of two objects and the distance between the centers is taken to be d. When the objects are not spherical or have irregular shape, then the direction of force is along the line joining the centers of mass and d is taken to be the distance between the two centers of mass. a) Is gravitational force a vector? Justify. b) What will happen to value of G on the surface of Mars? c) If two square plates are kept distance d apart from each other. What is the direction of gravitational force between the plates ADI 10T​
