Question:medium
Two brass spheres approaching each other with the same speed collide head-on elastically. After collision, if one of the spheres of radius \(R\) comes to rest, then the radius of the other sphere is:
Two brass spheres approaching each other with the same speed collide head-on elastically. After collision, if one of the spheres of radius \(R\) comes to rest, then the radius of the other sphere is:
Show Hint
For spheres of the same material:
\[
m\propto r^3.
\]
Convert mass ratios directly into radius ratios.
