battery maintains a constant potential difference V batt between them. In order to avoid dielectric breakdown, the electric
field in any region cannot exceed 4Vbatt/d.
Part A
What is the maximum thickness of the metal slab that can be used without causing dielectric breakdown?
3/4d
3d
4d
1/4d
Part B
If this maximum thickness is used, does the insertion of the metal slab affect the amount of charge stored on the
capacitor?
ANSWER:
yes
no
