Friction is caused by the uneven surfaces of touching objects
Then the separation between the two pennies will be O.354m.
To find the correct answer, we need to know about the electrostatic force of attraction.
<h3>What is the separation between the pennies?</h3>
- We have given with the information's,
- As we know that the charge of one electron is 1.6×10^-19C.Thus, the total charge on the penny will be,
- We have the expression for electrostatic force of attraction as,
, here given that the electrostatic force equal to the weight of the system.
- We have to find the separation between the pennies.
Thus, we can conclude that the separation between the pennies is 0.354m.
