You set out to reproduce thomson’s e/m experiment with an accelerating potential of 150 v and adeflecting electric field of magnitude 6.0 ×106 n/c(a) at what fraction of the speed of light do the electrons move? (b) what magnetic-field magnitude will yield zero beam deflection? (c) with this magnetic field, how will the electron beam behave if you increase the acceleratingpotential above 150 v?

a. v' = 24.22 x 10 ⁻³

b. β = 0.825 T

Explanation:

V = 150 V , E = 6.0 x 10 ⁶ N / C

a.

¹/₂ * m * v² = e * V

v = √ 2 * e / m * V

v = √ 2 * 1.76 x 10 ¹¹ * 150 v  = √ 5.28 x 10 ¹³

v = 7.26 x 10 ⁶ m /s

v' / c = 7.26 x 10 ⁶ m /s  / 3.0 x 10 ⁸ = 24.22 x 10 ⁻³

b.  

β = E / V

β = 6.0 x 10 ⁶ / 7.266 x 10 ⁶

β = 0.825 T

c.

When the increasing the accelerating potential speed it doesn't change the up wired the electric force and the magnetic force the electron be beat down more .

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

3. dark matter

empty space could also be a simple vacuum
