Best ResponseYou've already chosen the best response.0E=F/q E=8.4 N/8.8*10^6=9.5*10^7 N/C ve sign indicates the direction of Electric field is vertically upward.

Best ResponseYou've already chosen the best response.0if the sign is positive the direction will be downward?

Best ResponseYou've already chosen the best response.0okay now i finally got the problem thank you. but this one is different: An electron is released from the rest in a uniform electric field and accelerates to the north at the rate of 115m/s^2. What are the magnitude and direction of electric field (E)?

Best ResponseYou've already chosen the best response.0we know that F=ma, so on putting the value of m and a you will get force... and we know that the charge on electron...simply put all the values in eqn. E=F/q=ma/q you will get ur ans

Best ResponseYou've already chosen the best response.0the acceleration would be_115m/s^2 right? what would be the mass? and our q would be the electrons charge?

Best ResponseYou've already chosen the best response.0mass of electron is 9.1*10^31kg and charge on electron is 1.6*10^19C

Best ResponseYou've already chosen the best response.0this: (115m/s^2) ( 9.1*10^31kg) divided by 1.6*10^19C ?

Best ResponseYou've already chosen the best response.0how did you get this ( 9.1*10^31kg) ?

Best ResponseYou've already chosen the best response.0it is calculated value..you may learn it. u may also learn the charges and masses of another sub atomic particles

Best ResponseYou've already chosen the best response.0is it constant? can u show me how did u get it?

Best ResponseYou've already chosen the best response.0yes it is constant... and for further information please concern with wikipedia here u will get ur ans...

Best ResponseYou've already chosen the best response.0how about this: What are the magnitude and direction of the electric force on an electron in a uniform electric field of strength 2360N/C that points due East. the charge of electron is 1.6 x10^(19) ? how come? Force=electric field x charge electric field=2360

Best ResponseYou've already chosen the best response.0what are u asking alfers101?

Best ResponseYou've already chosen the best response.1The charge of an electron is always the same, it is a given ( and it should be negative though). You have to plug in. Pay attention to the units, write the units of the given. You have to still determine the direction. F= qE; plug in ; and since it is negative it should be in the opposite direction.
