What is the work zone by the field in moving a small positive charge from A to P? Given reason.

What are the factors on which the capacity of a parallel plate capacitor with dielectric depend?

The graph shown here shows the variation of total energy (E) stored in a capacitor against the value of the capacitance (c) itself. Which of the two is kept constant for this graph, whatever the charge an capacitor of the potential used to charge it?

Gauss law is true for any closed surface, no matter what its shape or size is. Justify.

The given graph shows the variation of charge q versus potential difference V for 2 capacitors C, & C₂. The two capacitors have same plate separation but the area of plate C₂, is twice that of C₁, which of the two graphs P & Q correspond to capacitors C₁ & C₂, why?
