A constant electric field with magnitude 1.50 ✕ 103 N/C is pointing in the positive x-direction. An electron is fired from x = −0.0200 m in the same direction as the electric field. The electron's speed has fallen by half when it reaches x = 0.190 m, a change in potential energy of 5.04 ✕ 10−17 J. The electron continues to x = −0.250 m within the constant electric field. If there's a change in potential energy of −1.06 ✕...
A proton is released from rest at point A in a constant electric field and accelerates to point B (see part a of the drawing). An electron is released from rest at point 8 and accelerates to point A (see part b of the drawing). How does the change in the proton's electric potential energy compare with the change in the electrons electric potential energy? O The proton experiences a greater change in electric potential energy, since it has a...
