please tell me where is the error here- 1 = \sqrt{}1 = \sqrt{}(-1) (-1) =\sqrt{}-1 \sqrt{}-1 = i^{}2 = -1 so we get 1= -1. what is the error here?

i think charge can flow upto the point where the switch is connected. After that there is no conducting path for flowing of the charge. But Imn't sure of it.

When a solid body is moving on any hard surface due to friction it will lose some very little part of its body; as when we take a broken piece of glass and rub it on the concrete surface, it loses some mass of its initial mass. so, what is the general formula of finding the lost mass due to...
