Consider the pith balls in the diagram:
Both of them has mass 'm' and charge 'q'. The question asks for the charge on both the pith balls.
The concept is a bit straightforward. But I am confused at the force distribution experienced by the pith balls.
My text tackles the problem with reference to the following diagram.
And taking ##Tcos\theta=g## and then using ##T=\frac{g}{cos\theta}## and then proceeding to find the charge.
The part I am confused with is that, if we consider the following image
why can't we resolve the vectors as shown in the image and use ##T=gcos\theta## and proceed?
Is it because the tension has a component perpendicular to that of 'g' ?
I am confused with the Free Body Diagram of forces. Is there any good article available on web?
