find what? force?
 one year ago

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

and i didn't get the question.. is it to find the electric field at any point on the cube?!

all edges have a charge
 one year ago

Mashy Group TitleBest ResponseYou've already chosen the best response.1
there 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?!

a charge is kept there? and we have to find E on that? _

hmm, so you want to find the net force acting on the charge.

It 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.
 one year ago

Mashy Group TitleBest ResponseYou've already chosen the best response.1
yea... 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 !!

they'd all have a common factor of \[k{q^2\over a^2}\]

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

dw: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 Group TitleBest ResponseYou've already chosen the best response.1
in the end i meant Fba=Fda* sorry
 one year ago

electrokid Group TitleBest ResponseYou've already chosen the best response.1
if 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
