The area of the plates of a parallel plate condenser is \[A\] and the distance between the plates is \[10mm\]. There are two dielectric sheets in it, one of dielectric constant 10 and thickness \[6mm\] and the other of dielectric constant 5 and thickness \[4mm\]. The capacity of the condenser is [MP PMT 1997]

• B. \[\frac{2}{3}{{\varepsilon }_{0}}A\]
• C. \[\frac{5000}{7}{{\varepsilon }_{0}}A\]        
• D.   \[1500\ {{\varepsilon }_{0}}A\]
