The elctric field as a fuctlon of position V/cm 6 4. 2 distance (cm) 3 1 7 CI 6 1. Extrapolate the electric field function in the negative range -7.01. Ensure you use at least seven points. 2. Compute the electric potential difference in this case from C-70 3. Extrapolate the electric field function in the positive range 107). Ensure you use at least seven points. 4. Compute the electric potential difference in this case from 071 5. What can you infer about the potential difference from C-7 +7] Justify 6. Compute the electric potential at O. 7. Say you released a proton from rest sitting at the origin would it roll up or down the track Justify 8. Calculate the work done on the proton during the ascent descent. ​
