In the given figure, each capacitor is of capacitance $$1 \mu F$$.Calculate the equivalen capacitance between A and B.

An infinite number of charges each equal to Q are placed along the x-axis at x=1,x=2,x=4,x=8,.......... and so on.Find the potential and electric filed at the point x=0  , due to this set of charges:

The electric potential in a certain region is expressed by $$V = 6x-8xy^2-8y + 6yz - 4z^2$$ volts. The magnitude of the force acting on a charge of $$2C$$ sityuated at the origin wil be:-

Two parallel plates have equal and opposite charge. When the space between them is evacuated, the electric field between the plates is $$2\times\ 10^5\ V/m$$. When the space is filled with dielectric, the electric field becomes $$1\times\ 10^5\ V/m$$. The dielectric constant of a dielectric material is:

The resultant capacity between point $$A$$ and point $$B$$ in the following circuit will be:

Four condensers are connected as shown in the figure. The effective capacity in $$\mu F$$ between the points $$A$$ and $$B$$ are :

Fig. shows a network of four capacitors. Determine the equivalent capacitance between points $$A$$ and $$B$$. If a $$10V$$ battery is connected between $$A$$ and $$B$$, how much total charge will be stored on the capacitors ?
