Question

an air filled plate condenser has a capacity of 2 picofarad The Separation of a plate is doubled and the interface between the plates affair with wax if the capacity is increased to 6pico farad with the electric constant of wax is
a)4
b)6
c)2
d)3​

Answer 1

Answer:

3..................

okkk

okkkkkkkk

Answer 2

Answer:

b) 6

Explanation:

by doubling the sepration capacitance would be half i.e. 1pf

so when capacitiy is increased to 6 pf then the dielectric insertion increase the capacitance 6 times
