Question

Which one of these quantities has a different dimension from the others?

Options

Choose one · Correct answer highlighted

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.
