What are the dimensions of stress ?
Correct answer: C. ML-1T-2
- A. MLT-2
- B. ML-2T-1
- C. ML-1T-2
- D. ML-T-1
Explanation
Stress = force/area. Force has dimensions M L T^-2 and area has dimensions L², so stress has dimensions M L T^-2 / L² = M L^-1 T^-2. MLT^-2, the likely mistaken choice, is the dimension of force rather than stress.

About Resistance and Resistivity
Resistance measures opposition to current in a conductor and follows R = V/I for an ohmic conductor, while resistivity is an intrinsic property of the material. Questions use R = ρL/A, examine effects of length, cross-sectional area and temperature, and distinguish resistance, resistivity, conductance and conductivity.
