Electrons execute 1.4*10^6 revolutions per sec in a magnetic field of flux density
seropon [69]

The charge of the electrons is 8.02 \times 10^{-19} \ C.

The given parameters:

  • <em>Number of revolution of the electron, N = 1.4 x 10⁶ rev per sec</em>
  • <em>Flux density, B = 10⁻⁵ T</em>
  • <em>Mass of electron, m = 9.11 x 10⁻³¹ kg</em>

<em />

The angular speed of the electron is calculated as follows;

\omega = 2\pi N\\\\\omega = 2\pi \ \frac{rad}{1 \ rev} \times 1.4 \times 10^6 \ rev/s\\\\\omega = 8.798 \times 10^6 \ rad/s

The charge of the electrons is calculated as follows;

F_c= m\omega ^2 r\\\\F_{B}= qvB = q\omega r B \\\\F_c = F_B\\\\m\omega ^2 r =  q\omega r B \\\\q = \frac{m\omega ^2 r}{\omega r B} \\\\q = \frac{m \omega }{B} \\\\q = \frac{9.11 \times 10^{-31} \times 8.798 \times 10^6}{10^{-5}} \\\\q = 8.02 \times 10^{-19} \ C

The charge of the electrons is 8.02 \times 10^{-19} \ C.

The complete question here:

Electrons execute 1.4*10^6 revolutions per sec in a magnetic field of flux density 10⁻⁵ T. What will be the value of charge of the electron?

I need help again :/
Kobotan [32]

Answer:

Hola

Step-by-step explanation:

Well if this is based off the first thing I answered, then 1. C

as I told you before, every time the x axis values go up one, the y values go up by x2 (aka times 2). Therefore it’s C.

2. It is linear because the unit change (amount it goes up aka slope) is the same since it’s alway x2. Hence the line on a graph would look linear

I don't under stand what is wrong.
MAXImum [283]

Answer:

In the first step, there is an issue when distributing the -3 to the terms inside of the parentheses. When multiplying the -3 to the -5, you would get an answer of +15, not -15.

The full correct process is:

(4m + 9) - 3(2m - 5) = 4m + 9 - 6m + 15

                                = 4m - 6m + 9 + 15

                                = -2m + 24
