The kinetic energy of proton and anti-proton (KE).
Answer to Problem 18P
Solution:
The kinetic energy of proton and anti-proton (KE)is 987.4MeV.
Explanation of Solution
Given Info:
The mass of K+is 493.7MeV/c2.
The mass of K-is 493.7MeV/c2.
Formula Used:
The formula to calculate wavelength is,
• ‘ ’ is the kinetic energy of the proton.
• ‘ ’is the kinetic energy of anti-proton.
• ‘ ’ is mass of K+.
• ‘ ’ is mass of K-.
The required reaction is
Applying conservation of energy to find the relativistic energy of proton and antiproton by adding the energy of each proton and antiproton along with the energy of and ,
As the velocity of proton and anti-proton is equal, the kinetic energy is
So the formula used to get the kinetic energy of each proton and antiproton is,
