Question
A -3.6 nC charge is on the x-axis at = -8 cmand a 4.3 nC charge is on the x-axis at = 14 cm . Part A At what point or points on the y-axis is the electric potential zero? Picture is the answer I had before, Help me with this if u can thx y= 66.4433 cm Your answer does not have the correct number of comma-separated te ANSWER 4: Deduction:-3% y= 66.4433-66.4433 cm ANSWER 5: y= 66.4433 cm Your answer does not have the correct number of comma-separated te ANSWER 6: y= 21.01122 cm Your answer does not have the correct number of comma-separated te ANSWER 7: y= 21.01122 cmExplanation / Answer
Net electric potential on y-axis at point P is
VP=V1+V2=0
KQ1/r1 +KQ2/r2=0
-3.6/sqrt(y2+82) +4.3/sqrt(y2+142)=0
sqrt((Y2+142)/(Y2+82))=4.3/3.6=1.1944
Y2+196=1.4267(Y2+64)
0.4267Y2=104.7
Y=15.66 cm
