Four charged particles are placed so that each particle is at the corner of a square. The sides of the square are 15 cm. The charge at the upper left corner is +3.0 microCoulombs, the charge at the upper right corner is -6.0 microCoulombs, the charge at the lower left corner is -2.4 microCoulombs, and the charge at the lower right corner is -9.0 microCoulombs.

do u know how to do vector addition??

kittiwitti1 · Answer

Our teacher did vector addition but I think it's wrong...

anonymous · Answer

ok.try doing the first one first.
first find out the force on the 3 microcoulomb charge due to every other charge separately with its direction.

kittiwitti1 · Answer

Well, the equation I got for a) was$$\Sigma F_x=F_{12}+F{13x}$$

kittiwitti1 · Answer

from my teacher that is

anonymous · Answer

instead of writing the equation,try it urself first by solving it diagramatically.then u wud hv ease in finding  out the direction of forces.

@iambatman ???? Yes....
@Rohitkhanna I did try but I have no idea what to do.
