Frequently asked questions
What question type is most common from this chapter?
Finding the dimensional formula of a physical quantity, or checking the dimensional consistency of an equation, is the single most frequently repeated question type.
Is error analysis tested numerically?
Yes — calculating percentage/relative error in a derived quantity (e.g. density from mass and volume measurements) is a standard recurring numerical.
