Thank you soo much, Where can I find these slides that you presented?

[@pansilmaluwa116]

👍

[@pansilmaluwa116]

Keep doing it great job👌

[@ayoo9963]

Pls why was the last part so complicated how were we suppose to know that

[@sumairfaiz700]

Why did we not take the given change in potential 1.62 V That should be the change in pE no?

[@layanodah5151]

The change in PE is equal to q × change in the potential so 47e × 1.62

miss, are we allowed to just write k? and sub in the value k? without stating the value of epsilon naught? for electric field questions

[@dylanscottmufandaedza8146]

why did you multiply the charge of the silver nucleus by 1.6x10^-19

[@ETphysics]

How many protons does a silver nucleus have?

[@zeidbadulla6652]

how did you get k 8.99*10^9 in 5c

[@ETphysics]

k is the unofficial constant for 1/4πε
