V1 + V2 + V3 =0
kq1 /d + kq2 /d + kq3 /d (route)2 over 2= 0
then i solved for q3 and i got -2.8x 10^-6 C
but the answer is -1.4 x 10^-6C
which means i forgot half somewhere..
thanks though! i think i can handle it!
wish me luck in physics 12 exam tomorrow! ahha
i'll very likely need all...
Electric Potential !
Homework Statement
Two charges are placed at the corners of a square. One charge, 4.0μC, is fixed to one corner and another, -6.0μC, is fixed to the opposite corner. What charge would need to be placed at the intersection of the diagonals of the square in order to make...
