Two capacitors ${\mathrm{C}}_1$ and ${\mathrm{C}}_2$ having capacitance 2 mF and 4 mF respectively are connected as shown in the figure. Initially ${\mathrm{C}}_1$ has charge 4 mC and ${\mathrm{C}}_2$ is uncharged. After long time closing the switch S :

• A

  Charge on both capacitor will be equal 

• B

  Electrostatic potential energy stored in both capacitor will be same

• C

  Electric field between the plates of capacitor ${\mathrm{C}}_1$ and ${\mathrm{C}}_2$ will be equal 

• D

  Potential difference between the plates of the capacitor ${\mathrm{C}}_1$ and ${\mathrm{C}}_2$ will be same
