Two protons, starting several meters apart, are aimed directly at each other with speeds of 2.00 * 105 m>s, measured relative to the earth. Find the maximum electric force that these protons will exert on each other.

Explanation:

Since, the two protons are at the initial state of point a and point b. Hence, total mechanical energy at point a and point b is as follows.

or,            

where,   = kinetic energy of two protons

So,      

Putting the given values into the above formula we will calculate the value of as follows.

                =

                =

Now, we will calculate the maximum electric field as follows.

      F =

         =

         =

Therefore, we can conclude that the maximum electric force that these protons will exert on each other is .

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
