Question

When a high-energy proton or pion traveling near the speed of light collides with a nucleus, it may travel 2.5 x 10-15 m before interacting. From this information, find the time interval required for the strong interaction to occur.

Answer 1

Step-by-step explanation:

It is given that,

When a high-energy proton or pion traveling near the speed of light collides with a nucleus,
`d=2.5* 10^(-15)\ m`

Speed of light,
`c=3* 10^(8)\ m\s`

Let t is the time interval required for the strong interaction to occur. The speed is given by :

`c=(d)/(t)`

`t=(d)/(c)`

`t=(2.5* 10^(-15)\ m)/(3* 10^(8)\ m/s)`

`t=8.33* 10^(-24)\ s`

So, the time interval required for the strong interaction to occur is
`8.33* 10^(-24)\ s`. Hence, this is the required solution.
