Two particles, an electron and a proton, are initially at rest in a uniform electric field of magnitude 564 n/c. if the particles are free to move, what are their speeds (in m/s) after 49.6 ns?

For electron

For proton

Explanation:

Given that

E= 564 N/C

Charge on electron

Mass of electron

Charge on proton

Mass of  proton

We know that

F = E q

F= m a

For electron:

F=  E q

m a = E q

V= U + a t

For proton:

F=  E q

m a = E q

V= U + a t

another example of kinetic energy would be,

kinetic energy   >     moving energy

hope that !                                         : )

i think it's 35 meters
