Two parallel plate capacitos of capacitencesC and 2C are connected in parallel and charged to a potential difference V_(0) . The battery is then disconnected and the region between the plates of the capacitor C completely filled with a material of dielectric constant 2. The potential difference across the capacitors now becomes-

Answer»

`V_(0)/4`
`V_(0)/2`
`3V_(0)/4`
`V_(0)`

SOLUTION : `V_(com)=(q_(1)+q_(2))/(C_(1)+C_(2))`
