Question 1
Part 1: Candidates were required to answer any five questions from this part.
State the dimensions of the following physical quantities:
- acceleration;
- pressure;
- density.
Observation
This question was very popular among the candidates and did not pose problem to most of the candidates, as they were merely asked to state, rather than derive the dimensions of the specified physical quantities. However, few candidates could not identify the difference between dimensions and units of the given quantities. Hence they gave the units and not the dimensions.
The expected answers are:
Quantity Dimension
1. Acceleration LT -2 2. Pressure ML-1T -2
3. Density ML-3
