Two protons move with uniform circular motion in the presence of uniform magnetic fields. Proton one moves twice as fast as prot
lubasha [3.4K]

Answer:

r₂ = 4 r

Explanation:

For this exercise let's use Newton's second law with the magnetic force

          F = q v x B

bold letters indicate vectors, the magnitude of this expression is

          F = q v B sin θ  

in this case we assume that the angle is 90º between the speed and the magnetic field.

If we use the rule of the right hand with the positive charge, the thumb in the direction of the speed, the fingers extended in the direction of the magnetic field, the palm points in the direction of the force, which is towards the center of the circle, therefore the force is radial and the acceleration is centripetal

           a = v² / r

let's use Newton's second law

           F = ma

           q v B = m v² / r

           r = \frac{qB}{mv}

Let's apply this expression to our case.

Proton 1

             r = \frac{qB_1}{mv_1}

Proton 2

             r₂ = \frac{q \ B_2}{m \  v_2}

in the exercise indicate some relationships between the two protons

*    v₁ = 2 v₂

    v₂ = v₁ / 2

*   B₂ = 2B₁

we substitute

           r₂ = \frac{q \ 2B_1}{m \ \frac{v_1}{2} }

           r₂ = 4 \frac{qB_1}{mv_1}

           r₂ = 4 r

Why does our solar system have a asteroid belt
amid [387]
Answer: The asteroid belt (sometimes referred to as the main asteroid belt) orbits between Mars and Jupiter. It consists of asteroids and minor planets forming a disk around the sun. ... Astronomers also assumed that Jupiter's gravity prevented the material in the belt from coalescing into larger planets.

What happened to the combined energy of the two sleds when they collided?
Komok [63]
Hi!
Here’s your answer:

What happened to the combined energy of the two sleds when they collided? It changed forms into another energy C. Because energy is conserved, the “lost” energy has actually been changed into other forms.

Hope this helps have a good day!!<3

The pressure extered by fluid at any given depth is exerted _____ in all directions
Blababa [14]

The pressure exerted by fluid at any given depth is exerted equally in all directions.

<h3><u>Explanation:</u></h3>

Pressure is defined as the force per unit area. Hydraulic force is the force that is exerted by liquid to a particle which is present somewhere inside the liquid. This pressure is exerted by the liquid particles from each part of the of the whole mass.

As far as the upper particles are concerned, the liquid exerts the force due to gravity, which acts downwards. Similarly, the particles which are down to the particle in liquid gives the reaction force which is based on Newton's third law of motion. This makes the force acts from all sides.

This is the reason why a particle which is submerged stays still, as there's no unbalanced force which can turn the particle.
