The surface charge density on an infinite charged plane is −1.70 x 10^−6 c/m^2 . a proton is shot straight away from the plane at 1.90 x 10^6 m/s . how far does the proton travel before reaching its turning point?

Acceleration of proton will be

Explanation:

We have given surface charge density of an infinite charged plate

Electric field due to infinite sheet charge is given by

Charge in proton is given by

So force on proton

Mass of proton

According to newtons second law force F = mass × acceleration

So

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
