Particles are displaced from their equillibrium position. They in turn displace neighbouring particles and then get back to their original postion.

A proton moves through a magnetic field at 20.3 % of the speed of light. At a location where the field has a magnitude of 0.0062

galina1969 [7]

Answer:

Force on the proton will be $.73\times 10^{-14}N$

Explanation:

We have given speed of proton is 20.3% of speed of light

Speed of light $c=3\times 10^8m/sec$

So speed of proton $v=\frac{3\times 10^8\times 23}{100}=6.9\times 10^7m/sec$

Magnetic field B = 0.00629 T

Charge on proton $q=1.6\times 10^{-16}C$

Angle between velocity and magnetic field $\Theta =137^{\circ}$

Force on the proton is equal to $F=qvBsin\Theta =1.6\times 10^{-19}\times 6.9\times 10^7\times 0.00629\times sin(137^{\circ})=4.73\times 10^{-14}N$

Consider the specific example of a positive charge q moving in the +x direction with the local magnetic field in the +y directio

Leto [7]

Answer:

Therefore the direction is in the positive direction of the z axes.

Explanation:

Let's recall that the magnetic force is given by:

$F_{B}=q(\vec{v} \times \vec{B})$

The unit vector of V is $\hat{i}$ and the unit vector of B is $\hat{j}$

So, the direction of the force will be defined as the cross product of i and j, and using the right hand rule:

$\hat{i} \times \hat{j} = \hat{z}$

Therefore the direction of the magnetic force is in the positive direction of the z axes.

I hope it helps you!

What is mean by gravitational force

Aleonysh [2.5K]

Answer:

Gravitational Force is a force that attracks two objects with mass. For example, you are being pulled onto this planet, and that's why when you jump upwards, you fall back down quickly. A fun fact is that every object, even the entire universe, are pulling all on each other, including you!
