Simulates 2D celestial object motions
The program takes input in the form of a file. The name of the file must be entered in the console.
Format of the file must be as follows:
->First line must contain no. of planetary objects who's motion is to be simulated
->Next, details about each object must be given in this order
->Mass
->X-coordinate of position
->Y-coordinate of position
->Radius
->Initial velocity(x component)
->Initial velocity(y component)
->Constant force (x component)
->Constant force (y component)
The constant force is constant with respect to global coordinates, and does not change with direction of motion of the body.
