Two metal spheres of capacitance ${C_1}$ and ${C_2}$ carry some charges. They are put in contact and then separated. The final charges ${Q_1}$ and ${Q_2}$ on them will satisfy
  • A$\frac{{{Q_1}}}{{{Q_2}}} < \frac{{{C_1}}}{{{C_2}}}$
  • B$\frac{{{Q_1}}}{{{Q_2}}} = \frac{{{C_1}}}{{{C_2}}}$
  • C$\frac{{{Q_1}}}{{{Q_2}}} > \frac{{{C_1}}}{{{C_2}}}$
  • D$\frac{{{Q_1}}}{{{Q_2}}} < \frac{{{C_2}}}{{{C_1}}}$
