Answer:

Explanation:
The kinetic energy possessed by particles will be

where,
M is the mass of the particle (7920938.3 MeV/c²)
c is the speed of the light
Also,
energy of the proton particle = 
where,
v is the velocity
m_p is the mass of the proton (938.3 MeV/c²)
since the energy is equal
thus,

or
![1-\frac{v^2}{c^2}=[\frac{2m_p}{M}]^2](https://tex.z-dn.net/?f=1-%5Cfrac%7Bv%5E2%7D%7Bc%5E2%7D%3D%5B%5Cfrac%7B2m_p%7D%7BM%7D%5D%5E2)
substituting the values in the above equation, we get
![1-\frac{v^2}{c^2}=[\frac{2\times 938.3 }{7920}]^2](https://tex.z-dn.net/?f=1-%5Cfrac%7Bv%5E2%7D%7Bc%5E2%7D%3D%5B%5Cfrac%7B2%5Ctimes%20938.3%20%7D%7B7920%7D%5D%5E2)
or

Hence,<u> the speed necessary for the specified condition to occur is </u><u>0.9714 times the speed of the light</u>
