I don't know why the answer is
wrong, I got K(final) = 1.1072x10^-15 J and K(initial) =
1.4576x10^-15J, with the work energy theorm I got q=(Kf-Ki)/(Vi-Vf)
= +5.48x10^-18 C
Your answer is partially correct. Try again. A moving particle encounters an external electric field that decreases its kinetic energy from 9100 eV to 6990 eV as the particle moves from position A to position B. The electric potential at A is-41.0 V, and that at B is +23.0 V. Determine...

Hi I just need to know if these statements are true or false and why!! 1. Electric field lines always point from higher to lower potential, meaning that a positive test charge would then seem to "fall" in the correct direction. 2. A student measures the potential between parallel plates A and B, and the meter reading is +30 V. The student concludes that there is a charge on plate B, but none on plate A. 3. If a capacitor...
