165601 Capacity of parallel plate capacitor is $10 \mu \mathrm{F}$, when gap between plates is $8 \mathrm{~cm}$, then what will be its capacity if gap is reduced to $4 \mathrm{~cm}$ ?

165602 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

165603 A parallel plate capacitor with air between the plates has a capacitance of $9 \mathrm{pF}$. The separation between the plates is $d$. The space between the plates is now filled with two dielectrics constant $K_{1}=3$ and thickness $d / 3$ while the other one has dielectric constant $K_{2}=$ 6 and thickness 2d/3. Capacitance of the capacitor is now

165604 Two metal plates having potential difference of $800 \mathrm{~V}$ are $2 \mathrm{~cm}$ apart. It is found that a particle of mass $1.96 \times 10^{-15} \mathrm{~kg}$ remains suspended in the region between the plates. The charge on the particle must be ( $e=$ elementary charge)
