2. Two spherical celestial objects, call them A and B have mass M1 and M, with radius R1 and R2 respectively. Initially they are at a distance d from each other. Now solve the following problems. A (a) What would be the gravitational acceleration on the surface of object A ? You should ignore B's presence in this case. (b) Find the escape velocity of object B. Again ignore A's presence. (c) Now lets say these two objects, A & B start to move towards each other dude to mutual gravitational attraction. Find the time when they will collide with each other. Express you answers in terms of the given pa- rameters and any universal constant.
