An electron with a speed of 1.2 × 107 m/s moves horizontally into a region where a constant vertical force of 5.2 × 10-16 N acts on it. The mass of the electron is 9.11 × 10-31 kg. Determine the vertical distance the electron is deflected during the time it has moved 19 mm horizontally.

0.85mm

Explanation:

It is given that,

Speed of the electron in horizontal region,

Vertical force,

Vertical acceleration,

Let t is the time taken by the electron, such that,

Let d_y is the vertical distance deflected during this time. It can be calculated using second equation of motion:

u = 0

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
