Question

Manten 16.2 Electric Potentials and Potential Energy Due to Point Charges 11. An electron is at the origin. a) Calculate the electron potential Va at a point A, x = 0.250 cm. b) Calculate the electric potential VB at a point B, X = 0.750 cm. What is the potential difference VB - VA. c) Would a negatively charged particle placed at a point A necessarily go through this same potential difference upon reaching point B? Explain.

Step by step and explain please! Alsp dont forfet to write the formula so i can follow along.
Thank u!

Date DELTA PONO a= e = 1.6x10c 8.250cm electora Do Origin electric Potential formula whoch is at a distance V=Kq 0.950cm at any point from charge - 0 K= constant =9x10 q=charge =al. 6x10 r= ? (for electron) for r=0.250cm r=0.250 x 10²m for r=0.750cm r=0.750x15²m V = K28 v=Kq 949 x G xil v = 9x10x1.6X10 0.750 x 102 - 0-250 x 15 =-57.68 108 Voltage V₂ = -19.2 X10 8 Volt I

and So, V = VA=-57.6 X108 VOLELTA WBO NO V = Vo = -19,2x108 Volt Potential difference between Point A and Point YBA = V-VA - kq - Kq R re ri VBA = Rare Voor 9x1Qx1.6 x 109 0.750X162 0-2507 solve this and we get = 38.4 x 108 БА- - So Ans. ca V=-57.6 X10° volt [b] Vo = -19.2 X178 volt Vp-VA = 38.48108 volt and

Date/ A negatively charged Patentert has charge but this charge o is not same as the charge of election, - but we know that = ne where e is charge of electrons for this situation, electric Potential diffuence will be V = V - Va МакФ Кар VBA - KOI - I 7 2 r. ker att BA & Q = ne tankeri-92 = VAB equation (2) e-g (sames VAN VBA So the potential difference will not be Same as election, but will be a multiple - Thank you

Date DELTA PONO for your knowledge We can see by this footaula here, electrip Potenttal v=ko that electic Potent paced due to any point charge depends upon charge value and distance between the point where coe have to measure Potential and the charge C) As and a increases a incarcases » V increases V decreases
