Question

Can someone please explain how to do part C of this question? Thank you! The answer is not y=2.353

Two positive point charges are arranged as shown below on a y-axis. The charges and there locations are are: q1 = +10.2 nC at (0, 8.80) mm and q2 = +6.0 nC at the origin. What is the x-coordinate of the point where a third charge (q3 = 47.2 nC) could be placed so that the net electric force on q3 is 0? 0 mm How would you describe the y-coordinate of this point (where the net electric force on q3 is zero) (try to answer this before doing any calculations)? this point will be in the region y

Explanation / Answer

B)F1=F2...

q1/(8.8-y)^2=q2/y^2...,,......(1)



y=3.819 mm from q2...
hence
this point will be in the region 0<y<4.4 mm

A)x=o

C)3.819 mm from q2...

D)from eqn(1) it is clear that y does not depend on any q3 values

for different q3 x and y values not changes remains same
it would be same regardless of q3 values
