Answer:
The potential difference between the plates is ![8.4\times10^{3}\ V](https://tex.z-dn.net/?f=8.4%5Ctimes10%5E%7B3%7D%5C%20V)
Explanation:
Given that,
Distance = 1.4 mm
Electric field strength ![E= 6.0\times10^{6}\ N/C](https://tex.z-dn.net/?f=E%3D%206.0%5Ctimes10%5E%7B6%7D%5C%20N%2FC)
Let the potential difference is V.
We need to calculate the potential difference between the plates
Using formula of electric field
![E=\dfrac{V}{d}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7BV%7D%7Bd%7D)
![V=Ed](https://tex.z-dn.net/?f=V%3DEd)
Where, V = potential
d = distance
Put the value into the formula
![V=6.0\times10^{6}\times1.4\times10^{-3}](https://tex.z-dn.net/?f=V%3D6.0%5Ctimes10%5E%7B6%7D%5Ctimes1.4%5Ctimes10%5E%7B-3%7D)
![V=8.4\times10^{3}\ V](https://tex.z-dn.net/?f=V%3D8.4%5Ctimes10%5E%7B3%7D%5C%20V)
Hence, The potential difference between the plates is ![8.4\times10^{3}\ V](https://tex.z-dn.net/?f=8.4%5Ctimes10%5E%7B3%7D%5C%20V)

This question sounds like it came after some activity where
some forces were observed. Since we were not there, and
we don't know what the activity was, we don't know what forces
were observed, and we have no clue to how they might be related
to the motion of the Earth around the sun.
Answer:
Based off the word "conserved" I would say
A. Conservation of Momentum.
