2
Consider two capacitors one with a planar area and other with stair like structure. The equivalent capacitance of the system can be found using the basic formula for a parallel plate capacitor and series combination of capacitors.

4
To find the Electric potential and Electric field due to infinite number of charges placed along the X-axis.

7
Potential difference between two rings with coinciding axes separated at a distance d.

9
The potential between the two plates of a capacitor when the capacitor is disconnected and positive charges are added to its plate.
10
Potential of a condenser. Try different combinations in such a way that the capacitor becomes fully charged.

In the adjoining diagram, the condenser will be fully charged to potential if :

A
and both are open
B
and both are closed
C
is closed and is open
D
is open and is closed.
