E=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.

okay 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)?

we 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

the acceleration would be_115m/s^2 right? what would be the mass? and our q would be the electrons charge?

mass of electron is 9.1*10^31kg and charge on electron is 1.6*10^19C

ans will be 6.5*10^48 N /C

this: (115m/s^2) ( 9.1*10^31kg) divided by 1.6*10^19C ?

it is calculated value..you may learn it. u may also learn the charges and masses of another sub atomic particles

is it constant? can u show me how did u get it?

how 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

what are u asking alfers101?

The 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.
