Question
2) If we double the distance between the plates of a parallel plate capacitor while keeping the area of the plates constant, what happens to the capacitance?
Answer
3) What happens to the potential energy between two point charges as their distances are cut in half?
Answer
1. its surface must be all the same electric potential 2. its entire volume except for its surface must be the same electric potential 3. different regions may have different potentials 4. the electric potential must be zero everywhere inside it 5. the electric potential is proportional to 1/r inside the material where r is the distance from the center
Explanation / Answer
different regions may have different potential b)2. the capacitance is reduced to 1/2 of its original value the capacitance is reduced to 1/2 of its original value increases by a factor of 2 a)3. different regions may have different potential b)2. the capacitance is reduced to 1/2 of its original value
