Capacitance of isolated bodies - class-XII

Question 1 of 17

The capacitance of an air filled parallel plate capacitor is $10\times {10}^{-12}F$. The separation between the plates is doubled and the space between the plates is then filled with wax giving the capacitance a new value of $40\times {10}^{-12}F$. The dielectric constant of wax is:

  1. $12.0$
  2. $10.0$
  3. $8.0$
  4. $4.2$
