fyi ... the electric field would actually be 5000 but let's use 1000. The force on the electron would be Eq=1000*1.6E-19=1.6E-13. The weight (W) of the electron near the surface of the earth would be mg=8.93E-30. Thus F/W = 1.79E16 N/N

the mass and charge on an electron are physical properties you can find in your text ...or google

oh!! thanks!! btw, last question, i hope u respond. it says in my text that the mass of an electron is 9.1 E-31kg. how did it become 8.93E-30?

it didn't ... you should note that mass and weight are two different things

i get it now. thank you so much! i feel so dumb with my previous questions. thanks for your patience

Does the 'compare it with the weight of the electron' means we need to divide the Force with the Weight?

Also, shouldn't 1000*1.6E-19 be equals to 1.6E-16?

could you please elaborate where 1.6 E - 10 and 1.6E = 13 is from? also the -30 in the weight of the electron05/22/21
