In electron-volts (ev), calculate the dechic of the center of the circle. potential energy placed

4- An electron in an x-ray machine is accelerated through a potential difference of 5*104 V before it hits the target. The change in electric potential energy is: (e = 1.6*10-19 C)a) -8*10-15 Jb) 8*10-15 Jc) 5*10-13Jd) 9*10-12J 5- A proton is released from rest at the origin in a uniform electric field in the positive x direction with magnitude 3000 N/C. The change in the electric potential energy of the proton–field system when the proton travels to x =5 m is: (e = 1.6*10-19 C)a) 24*10-16Jb) -24*10-16 Jc) 5000 Jd) 1000 J

An electron at position A at 2.5×10–11m form the nucleus of an atom as shown in the picture if the electron moves to position B at 4.2×10–12m from the nucleus. What is the potential difference during the movement of the electron from point A to point B?      (e= 1.6×10–19C) A)28V B)-34.5V C)-30V D)-23.4v
