Electrostatics Question 266
Question: A parallel plate capacitor is connected to a battery. The plates are pulled apart with a uniform speed. If x is the separation between the plates, the time rate of change of electrostatic energy of capacitor is proportional to [CPMT 2002]
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: C
Solution:
Capacitance will increase but not 5 times (because dielectric is not filled completely). Hence new capacitance may be 200 mmF.
