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).

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).

Two stars each of one solar mass (= 2xxl0^30 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).

Two stars each of one solar mass (= 2xx 10^30 kg) are approaching each other for a head on collision. When they are a distance 109 km, their speeds are negligible. What is the speed with which they collide? The radius of each star is 104 km. Assume the stars to remain undistorted until they collide. (Use the known value of G).
