LADP-14 Hoʻoholo ʻana i ka uku kikoʻī o ka Electron – Kiʻi Hōʻike Hōʻikeʻike Kiʻekiʻe

LADP-14 Ka Hoʻoholo ʻana i ka uku kikoʻī o ka Electron – Ke Ana Hoʻohālike

ʻO ka wehewehe pōkole:

LADP-14 Determining Specific Charge of Electron is designed to determine the specific charge or the electron charge and mass ratio, hiki i nā haumāna ke aʻo i nā ʻano neʻe o ke kukuna electron i loko o ka uila a me ka mākia, a e ana i ka ʻāpana geomagnetic.

E hoʻouna i ka leka uila iā mākou

Nā hoʻokolohua

1. E ana i ka nui o na rula o ka nee ana o ka electron ma ke kahua uwila a me ke kula.

a) Hoʻololi uila: electron + transversal electric field

b) Nānā uila: electron + longitudinal electric field

c) Ka hoʻoheheʻe mākēneki: electron + transversal magnetic field

d) Ka hoʻopololei ʻana i ka manaʻo hoʻokalakupua: electron + longitudinal magnetic field

2. E hoʻoholo i ka lākiō e/m o ka electron a hōʻoia i ka hoʻohālikelike polar coordinate o ka neʻe ʻana o ka electron spiral.

3. E ana i ka mea geomagnetic.
