An air filled parallel plate condenser has a capacity of 2 pF. The separation of the plates is doubled and the interspace between the plates is filled with wax. If the capacity is increased to 6 pF, the dielectric constant of wax is
Text Solution
Verified by ExpertsThe correct answer is:
D
Doubling the separation of plates will halve the value of capacitance equal to 1pF. Now dielectric insertion will increase the capacitance K times.
