Is this question on electric potential solvable? Ive tried everything. any ideas?
A charge of -1.9 × 10-9 C is at the origin and a charge of 9.4 × 10-9 C is on the x-axis at x = 3 m. At what two locations on the x-axis (xpositive, xnegative) is the potential zero?
The Attempt at a Solution
heres what i did...
kq1/r1 = kq2/r2
first i canceled k because its on both sides, and a constant..
then i solved for r1...
r1 = r2q1/q2
then i added the values...
r1 = 3(-1.9e-9) / (9.4e-9)
answer = .606
this is wrong... please help!!! thanks
