Best ResponseYou've already chosen the best response.1that place u assumed as 0,0,0 we have to find there due to rest 7 charges

Best ResponseYou've already chosen the best response.1no. force at any point on the cube. so, a point P on the cube.

Best ResponseYou've already chosen the best response.1and i didn't get the question.. is it to find the electric field at any point on the cube?!

Mashy

Best ResponseYou've already chosen the best response.1there is a difference between vertices and edge you know :P.. all charges are on the VERTICES.. so you need to find electric field at any point on an edge?!

Best ResponseYou've already chosen the best response.0a charge is kept there? and we have to find E on that? _

Best ResponseYou've already chosen the best response.0hmm, so you want to find the net force acting on the charge.

Best ResponseYou've already chosen the best response.1It does not matter at what corner you find the net force. use the 3D distance vectors. The individual forces would be way easier that way.

Mashy

Best ResponseYou've already chosen the best response.1yea... just use position vectors as marked.. and keep your Forces in i j k format.. and then finally add them up and get the magnitude !!

Best ResponseYou've already chosen the best response.1they'd all have a common factor of \[k{q^2\over a^2}\]

electrokid

Best ResponseYou've already chosen the best response.1just be careful with the signs.. since the forces will be directed along the position vectors but in opposite direction

Best ResponseYou've already chosen the best response.1dw:1364821535025:dw Naming them like that for meanwhile. Now what I have is, \[\large F_{DA}=\frac{kq^2}{a^2}\] \[\large F_{CA}=\frac{kq^2}{\sqrt{2a}^2}cos45^0\] Fca=Fba am i correct with the magnitudes till here?help me determining the directions too! i want to clarify everything tilll this point first.

DLS

Best ResponseYou've already chosen the best response.1in the end i meant Fba=Fda* sorry

electrokid

Best ResponseYou've already chosen the best response.1if you mean \[F_{CA}=\frac{kq^2}{a\sqrt{2}}\] then you are correct. since all charges are alike, the forces are repulsive and act along the distance vectors from other charge to A.\\ in my above diagram I give two such directions. look it up

DLS

Best ResponseYou've already chosen the best response.1yes i meant a root 2 only sorry!

electrokid

Best ResponseYou've already chosen the best response.1"components of a force" you are talking about magnitude. do not include that cos... it'd show up automatically with the vectors.

electrokid

Best ResponseYou've already chosen the best response.1when you take vectors like they are, all the things come with it like a package.

DLS

Best ResponseYou've already chosen the best response.1okay so dealing with only mag,im correct till here?

electrokid

Best ResponseYou've already chosen the best response.1yes. but if you take cos 45, you'd have to take unit vectors.. this increases your work. my advice, do not take that cos45 and simply find the vectors

Best ResponseYou've already chosen the best response.1yes i eliminated that ,rest is correct right? and just that a root 2 thing
