1. The problem statement, all variables and given/known data A -14.1 nC charge is located at position (x,y) = (2.48 cm, 1.24 cm). At what (x,y) position is the electric field -262600.0i? (Enter your x position first followed by the y position.) 2. Relevant equations E = kQ/r2 E = electric field strength k = 9 x 109 r = distance to the point from the charge 3. The attempt at a solution E = kQ/r2 ∴ r = √(kQ/E) r = 0.02198 original position: (0.0248m, 0.0124m) electric field: -262600.0i, unit vector 'i' indicates only x component, no y component: therefore y component is the same (electric field vectors go straight in toward -'ve charge) therefore x-component is.. 0.0248 + r =0.0248 + 0.02198 = 0.04678m final answer: (0.04678m, 0.0124m) Originally what I did was 0.0248 - r =0.0248 - 0.02198 = 2.82E-3 final answer: (2.82E-3m, 0.02198m) the computer rejected this. The computer only accepted (0.04678m, 0.0124m) as the correct answer I was wondering... is the other answer equally as valid or am I missing something?
