Best ResponseYou've already chosen the best response.1How would you actually do this? Well, define E2 to be on the xaxis, so \[E_{2(x)}=E_2\]\[E_{2(y)}=0\] And\[E_{1(x)}=E_1\cos(60)\]\[E_{1(y)}=E_1\sin(60)\]Add the x and y components

Best ResponseYou've already chosen the best response.0theree charges are at the corners of an equilateral triangle as shown in fig below , calculte the electric feild at the position of tha 2.00 micro colum charge due to the 7.00 micro columb and 4.00 micro columb charges.(b) use ur answer to detrmine the force on the 2.00 mdw:1349627210442:dwicro columb chare.

Best ResponseYou've already chosen the best response.1+ve direction=right E1x=\[\frac{4* (9*10^9)}{r^2}\] E2x=\[\frac{7* (9*10^9)}{r^2} cos(60)\] E2y=\[\frac{7* (9*10^9)}{r^2} sin(60)\]

Best ResponseYou've already chosen the best response.1\[E=F/q\]Multiply by the charge Sorry! In my earlier calculations it should have been MICRO coulombs multiply each by 10^6!
