Question

Detailed solution would be very appreciated, thanks~

Figure 2 shows the electric potential V(x) measured as a function of position along the x-axis. An electron is placed at a2 and a proton is placed at x_4. Both charges are initially at rest (v = 0), then they are released and can move freely along the x-axis. Assume the only force on each charge is due to the electrostatic potential (the charges do not interact). At what locations will each charge be moving the fastest? a) electron at x_1, proton at x_3 b) electron at x_3, proton at x_5 c) both electron and proton at x_3 d) electron at x_2, proton at x_4 e) electron at x_1, proton at x_5

Explanation / Answer

STEP1: observe the graph of potential carefully.you will find x1 is point of the highest poential and x3 the lowest.

STEP2:Now recall the fact that electron will move towards higher potential being negatively charged and proton will move towards lower poential.

STEP3:so electron being on x2 will move towards x1 at which it will have towards x1 where it will have maximum velocity. And proton at x4 will move towards x3 and here it will have maximum velocity.

so option 'a' is the answer.

rate me if it was helpful.thanks
