Two stars each of one solar mass (= 2 × 10^(30) kg) are approaching each other for a head on collision. When they are a distance 10^(9) km, their speeds are negligible. What is the speed with which they collide ? The radius of each star is 10^(4) km. Assume the stars to remain undistorted until they collide. (Use the known value of G).
