Two stars each of mass `M` and radius `R` are approaching each other for a head-on collision. They start approaching each other when their separation is `rgt gtR`. If their speed at this separation are negligible, the speed `v` with which they collide would be

Two stars each of 1 solar mass ( = 2 xx 10^(30) kg ) are approaching each other for a head-on collision. When they are at a distance 10^(9) km apart their speeds are negligible . What is the speed with which they collide? The radius of each star is 10^(4) km. Assume the starts to remain undistorted untile they collide, G = 6.67 xx 10^(-11) Nm^(2) kg ^(-2) .

Two starts each of one solar mass (=2xx10^(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).
