Practice question
Question
Which one of these quantities has a different dimension from the others?
Explanation
Work, energy, and torque share the same dimensional formula \[ML2T−2\], while pressure is \[ML−1T−2\]. As per NCERT Class 11 Chapter 2, dimensional analysis checks correctness and SI units define base and derived quantities. This principle confirms that Pressure is correct because its dimensions and unit match the physical quantity asked.
