- Homework Statement
- There are two discks rotating with angular velocity w and with radius R and 2R. The distance from there centres is 4R. Find the probability of a particle, that was rotating on the board of the smaller disck, to shock with the bigger after it leaves de disck.
- Relevant Equations
- V=wr , P(E)=N(E)/U
There are two points of the smaller disck such that a line is tangent to the two discks and passes by that point. If the particle leaves of any point belongin to the arch that connects these two points, then it will hit the other disck. So I managed to calculate the value of this arch and divide it by 2π. But I got the wrong answer. Is this correct ?
