An electron is accelerated through 2.70 103 v from rest and then enters a uniform 1.40-t magnetic field. (a) what is the maximum magnitude of the magnetic force this particle can experience?

To solve the exercise it is necessary to apply the concepts of Mangenetic Force and Energy generated by electric potential.

By definition we know that the energy within an electron through voltage can be expressed as

Where,

e= charge of electron

V= Voltage

The kinetic energy of a moving system can be expressed as

Where,

m = mass

v = Velocity

For energy conservation we have to

Solving to find v,

On the other hand we have that the Magnetic Force can be expressed as,

Where,

q=charge of proton

v=velocity

B= Magnetic field

Angle between the magnetic field and the velocity vector (It is perpendicular in this case)

Using the previous equation from velocity in the Force equation we have,

PART A) Replacing the values to find the force we have,

What happens when you throw a basketball up

toward the hoop? If you are lucky, the ball sinks

into the net, scoring two points before dropping

back down to the ground. The basketball isn’t

that heavy, so why doesn’t it stay up in the air

saying, “What comes up must come down”?

This saying is a simple explanation for what

causes the basketball to fall back to the ground.

It is being acted on by an invisible force called

gravity, which is the basic force in the universe

that attracts all objects to each other.

1 Gravity has existed since the beginning of the universe. It is hard to understand how or why it

works, but we know it is always there because it holds everything in the universe in place. First,

you need to understand that there is a gravitational attraction between you and Earth, between

Earth and the Moon, and between Earth and the Sun. Even though you can’t feel it, the

gravitational attraction between you and Earth is what keeps your feet planted firmly on the

ground. Imagine spinning around and around on a merry-go-round. As long as you are holding

on, then you stay on the merry-go-round, but if you ever let go, you will fly off and land on the

ground. This is a useful analogy in visualizing the gravitational attraction between Earth and

you. Earth is spinning on its axis and thanks to gravity, you are held to your position on Eart

rather than flying out into space. Explanation: this is what i can do!:)
