ANSWER: The principles you discover like the that you estimate use simply if costs can be looked at as an ongoing water that can spread by itself on people surface, it doesn’t matter what highest, and also have no White Sites dating density. Naturally, an instance as you determine, which have 5 too-much electrons is in not a chance such as for instance a liquid and i perform guess that sets from 5-0 so you can 0-5 may be the delivery over a time. In theory, the 5 electrons do plan by themselves so as that for every was since far away on the other cuatro that you can, but there would not be a different sort of like shipping.
QUESTION: Would it be it is possible to in order to suspend an enthusiastic electron via electrostatic levitation in the a uniform magnetized field? If in case this new current is decreased adequate so the electrostatic force on the electron is actually lower than the new push due to this new electron’s pounds carry out the new electron up coming experience a beneficial ‘fall’ owed in order to the law of gravity?
I am inquiring this simply because I am curious if placing a great positron in the an effective consistent magnetic field (during the vacuum pressure) and you can reducing the voltage to a highly brief really worth in order for the newest electrostatic push is lower compared to weight manage trigger a beneficial positron to as well as sense an excellent ‘fall’. Whenever they did feel an autumn it could be determined in the event it would slip up or downward.
By the inertial bulk After all new proportion of the push you apply at they split up by its acceleration, this means that their effectiveness getting accelerated
I’m 17 yrs . old plus the united kingdom going to data physics within college or university inside sep and was just interested in which because the our topics this present year is electronic phenomena and you may i chatted about millikan’s petroleum get rid of experiment and this searched an equivalent sort of suspension if the electrostatic force and force on account of the law of gravity was in fact balanced.
Today, it is known so you can over the top precision your inertial size of a good positron is equal to new inertial bulk off an electron
ANSWER: It is always nice to see young folks asking interesting questions. First, I need to correct one thing: everywhere you refer to a “magnetic field” you should say “electric field”; a magnetic field exerts no force on a charge at rest which is what you want to observe, la Millikan. (A more correct way, relativistically, to say this would be that they have equal momenta for equal speeds.) I believe it is true that nobody has ever “weighed” a positron by measuring the force it experiences in a gravitational field. But, if the gravitational mass were different from the inertial mass, this would fly in the face of the theory of general relativity. But, let’s talk about the feasibility of your experiment. The mass of an electron is about 10 -30 kg so its weight would be about 10 -29 N (taking g?10 m/s 2 ). The electron charge is about 1.6×10 -19 C and so the electric field required to levitate an electron would be 10 -29 /1.6×10 -19 ?6×10 -11 V/m. Suppose we use a parallel plate capacitor to create this field. The charge density ? on a plate with field E is about ?=?0E?10 -11 x6x10 -11 =6×10 -22 C/m 2 which would correspond to an electron density on the plates of about 6×10 -22 /1.6×10 -19 ?0.004 electrons/m 2 ! This would correspond to about one electron for every 250 square meters! That would not give a very uniform field would it? There is no such thing as a uniform surface charge density because charges in nature do not comprise a continuous fluid; so really tiny uniform fields are not possible. I did all that just for the fun of it, but there is an even more serious considerationthe earth itself has an electric field near the surface of typically 100 V/m pointing down, so an electron would be repelled upward. To do your experiment you would have to get rid of that field and I do not believe that it would be possible to be assured that you could make the residual field much less than your 6×10 -11 V/m. Back to the drawing board! Keep asking those hard and interesting questions, though, and good luck with your university studies.
