Two heavy objects of masses 1 kg and 2 kg are moving towards each other under the mutual gravitational force of attraction between them. At a particular instant,
distance between them is 1 m. Find the acceleration of the object of mass 2 kg in terms
of the gravitational constant G.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
