There positive partical of equal charge + 11.0 C are located at the corners of an equilateral triangle of side 15.0cm calculate the magnitude and the direction of the net force on eash partical ??
i think first
15 cm \100 = 0.15m
and then
F12 = K(Q1 Q2\r^2
f13=....
the same
BUT my qustion is how i can get the dirction with the 2 component ?? X & Y
can any 1 expline that 4 me pllz :)
thank u all
