Answer:
The relationship between the initial stored energy and the stored energy after the dielectric is inserted
is:
c)
Explanation:
A parallel plate capacitor with that is connected to a voltage source
holds a charge of
. Then we disconnect the voltage source and keep the charge
constant . If we insert a dielectric of
between the plates while we keep the charge constant, we found that the potential decreases as:
The capacitance is modified as:
The stored energy without the dielectric is
The stored energy after the dielectric is inserted is:
If we replace in the above equation the values of V and C we get that
Finally
Answer:
A
Explanation:
The acceleration of an object is directly proportional to its net force.
