like i have 1, 18000 volts, the second was 9000 volts, and the third also 9000 volts but the coulumb charge was -2, instead of 2 like the first so does that mean the final voltage is only 18000, so a negative couloumb charge actually subtractsf rom the total voltage?

ur right about the force part, i meant it i don't use it in the equation to find the Force magnitude, then i can draw FBD's to see which way itll go , cause of positive or negative, thanks a lot man! So for the Voltage equation, if one q is -2 microcouloumbs then i minus the whole kq1/r term right

i have an exam tomorrow and i just wanted to know , are you saying there's no way to tell from the info i sent? *sigh* nvm..

the formula v = kq1/r +kq2/r if a charge is -2 micro couloumbs for instance is that put into the equatoin and it becomes minused instead or the sign doesn't effect q in the formula cuase i remmeber in the f = kq1q2 the sign has no effect

no no i just want a simple anaswre i just meant weather acceleration should be -ma or +ma

I have a 1kg weight on a rmap inclined 20degrees being pulled upwards and to the left *******- ***********- ************** - ******************- in that motion above(look at dashes only), is it -ma or +ma? so the equation is -a = t - mgsin20 or a = t - mgsin20 I am just wondering if a...

oh roger that thanks

yup i knew of that i got mass, I am looking for acceleration but what's force f = q * e right i got e just don't know what q is (what they mean by q = +e)

Determine the acceleration of a proton (q = +e, m = 1.67 E -27) in an electric field of intensity 500 N/C. How many times is this acceleration greater then that due of gravity I'm not so understanding on todays lessons teh 2 formulas I can recall are f = q*e and e = f/q but i don't see...

one golden question does a higher K value mean more mass? or not

im tyring a ISP for physics which detrmines were the sprign will land when shot off a frame, with the target being 3 m away we got this formula d (x) = [1/9.8 * k/m ] * x square where x is the extension needed to make it reach d (x) which is 3 m my quesiotn is anyways, does a higher K value...

i get 4 N when using C and 6N when using B shudnt they be teh same for C -fnet + 5 =1 fnet = 4 for b -4 + fnet = 2 fnet = 6

i can't see anything you may have done wrong, anyone else see diffrently

is this right then? t1 = 4 N t3 = 5N t2 = 1 N (difference between 2 ends?) letmeknow thanks

If w = 1.0 rad/s 0-----0-----0-----0 lenght 1 = 2 m lenght 2 = 3 m lenght 3 = 4 m each circl is a object weighing 1 kg. find center of rotation and tension in the massless rods getting center of rotation was easy but tension.. well i know if there's 3 objects, to get...
