Final answer:
The separation of the plates of the parallel-plate capacitor is approximately 1.328 mm.
Step-by-step explanation:
To find the separation of the plates of a parallel-plate capacitor, we can use the formula:
d = σ / (ε0 * v)
where
d is the separation between the plates
σ is the surface charge density
ε0 is the permittivity of free space
v is the voltage between the plates.
Plugging in the given values:
d = (7.0 * 10-9 C/m2) / (8.85 * 10-12 C2/N*m2 * 6.0 V)
d = 1.328 * 10-3 m
Therefore, the separation of the plates is approximately 1.328 mm.
