Electrostatic P...

Some charge is being given to a conductor. Then its potential:

Point A is at a lower electrical potential than point B. An electron between them on the line joining them will

A pendulum ( positively charged and hinged at some length above the plate) is swinging above a parallel plate (infinitely large and having negative charge),now consider the following statements, (consider gravity)

 In context of a capacitor , which of the following statement is correct?

A charge $$q$$ is placed at $$A(2,3,3)$$ in the $$XYZ$$ co-ordinate system. Find the electric potential at $$B(-2,3,3)$$

The capacitance of a parallel plate capacitor with air as dielectric is C. If a slab of dielectric constant K and of the same thickness as the separation between the plates is introduced so as to fill 1/4th of the capacitor (shown in figure), then the new capacitance is

Two point charges, each of charge $$q$$, are placed at a separation of $$2a$$. The electric potential at their midpoint will be :

In given circuit, $$C_{1}=C_{2}=C_{3}=C$$ initially. Now, a dielectric slab of dielectric constant $$K=\frac{3}{2}$$ is inserted in $$C_{2}$$.
The equivalent capacitance become

The potential difference between the two plates of a parallel plate capacitor is constant. When air between the plates is replaced by dielectric material, the electric field intensity :

The difference in the effective capacity of two similar capacitors when joined in series and then in parallel is $$6 \mu F$$. The capacity of each capacitor is
