I think it is C because mass makes motion slower
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.

B)comet nuclei are not uniform in composition
<u> </u> <span><span> No. Neutron stars are the remnants of very large stars that have supernova'd. Anything below 1.44 solar masses becomes a dwarf, anything above 5 solar masses becomes a black hole. Everything in between becomes a neutron star (or quark star, but it's not proven).</span>
