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
