im having trouoble with part a myself i am using vne=J i have to convert km/s to m/s cm^-3 to m^-3 and e is 1.6e-19 i plug 500000*840*1.6x10^-19 but its wrong can i get help U_U ?

dont you have to use half angle identities to get integral of cos^2 ?

An Electron is Projected An electron is projected with an initial speed of 2.4 x10^5 m/s directly toward a proton that is fixed in place. If the electron is initially a great distance from the proton, at what distance from the proton is the speed of the electron instantaneously equal to twice...

nvm it was just the negative sign i was missing n.n

my numbers are Vx= 1.2 x 10 ^5 Vy=1.7x 10^3 and E= (105 N/C) j first i tried to get the acceleration with the equation a = eE/m 1.602x10^-19 * 105 / 9.11x10^-31 and i get 1.844 x10^13 i think i did the math right but still it says its wrong... anyy ideas...

im having the same trouble with the acceleration i did the same process he did and my webassign says its wrong..

true :O im going to try it and see what comes out :O

but something must be wrong because like i said earlier the webassign says its wrong :S u___U

i just need to get this question over with i tried and tried but i couldn't get the right answer plss anyone u.u 1. Homework Statement point charges q1 = -6q and q2 = +3q are separated by distance d. Locate the point (measured from the origin at q1) at which the electric field due to...

wahhhh thxx alot you really helpd me a whole lot xD im pretty sure i would never have gotten the right answer alone thanks (:

can i get like an m*g*tan(19)

i think the angle is given so we can solve use sin(19) = x/10 and get how much the ball is being pushed by the other charge and i see that both charges have the same amount and same charge that means the are pushing away on each other but i really can figure out what equation to use U_U

this is my first time posting here in the forums right now I am really stuck with this problem i already tried solving it on my own but i can't i will really apreciate any feedback or hint i could use to solve it U_U Estimating Charge Two hard rubber spheres of mass ~20 g are rubbed...
