Sir George Stokes has revealed one to v , the speed at which a decline out-of precipitation falls, is provided with because of the formula
In consequence of the brand new viscosity otherwise friction of one’s air small government do not fall with a continuously accelerated velocity, however, in the future reach a performance and this stays uniform toward other individuals of one’s slide; small one’s body new much slower so it speed.
We are able to similar to this discover amount of a decrease, and may also hence, while the told me significantly more than, assess just how many falls and so the quantity of electrified dust.
It’s a straightforward number to obtain because of the electricity strategies the fresh new full amount of power in these dirt; and therefore, as we know what number of dirt, we can conclude at once the fresh new costs for each particle.
If X ‘s the electric force, e the newest fees on miss, and you will w the pounds, i have, if you have balance
It was the procedure for which I basic determined brand new charge toward particle; H. A beneficial. Wilson has actually since utilized a less complicated means oriented into adopting the principles: C. Leer más
