A charge ‘q’-is carried from A to B through two different paths ACB and ADB. In which path more work is done? Justify.

Free rotation is possible with respect to a C-C bond in the case of alkanes. b) Draw Newman's projections of the two conformers of ethane. Which among these is more stable? Justify.

Equipotentiai surface is a surface on which the electric potential is the same at every point:- A point charge +q Is placed at the centre of a sphere of radius B. An other point charge +q is take from a point A to another diametrically opposite point B on the surface of the sphere. Calculate the work done for this.
