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

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
