Question

Two identical geostationary satellites are moving with equal speeds in the same orbit but their sense of rotation brings them on a collision course. The debris will (a) fall down (b) move up (c) begin to move from east to west in the same orbit (d) begin to move from west to east in the same orbit

Answer 1

Since both the satellites are having velocities equal and opposite to each other, after collision, both will have net momentum zero along the original direction. Hence, the debris will fall down towards center of earth.

I hope it will help you......
