Answer:
The new energy density is same as initial energy density u0 as it is independent of plate dimensions
Explanation:
As we know that energy density is total energy per unit volume
so we know that isolated plates of capacitor is placed here

here we have energy density given as

so we have

so it is independent of the dimensions of the plate while total charge on the plates is constant always
so energy density will not change and remains the same
Answer:
So increasing the voltage increases the charge in direct proportion to the voltage. If the voltage exceeds the capacitors rated voltage, the capacitor may fail due to breakdown of the dielectric between the two plates that make up the capacitor.
