Detailed Solution
Download Solution PDFCONCEPT:
- Measurement of any physical quantity involves comparison with a certain basic, arbitrarily chosen, internationally accepted reference standard called unit, and a Dimension is a mathematical tool used for studying the nature of physical quantities.
- The basic concept of dimensions is that we can add or subtract only those quantities which have the same dimensions.
- And the dimensional formula is defined as the expression of the physical quantity in terms of mass, length, and time.
EXPLANATION:
Strain:
- The ratio of change in configuration to the original configuration is called strain.
- As the strain is the ratio of two like quantities, it has no units and no dimensions.
- and has no dimension.
- Its dimension can be expressed as M0L0T0.
The correct answer is M0L0T0.
| Quantities | Dimension |
| Stress | M1L-1T-2 |
| Frequency | M0L0T-1 |
| Dynamic viscosity | M1L-1T-1 |
| Kinematic viscosity | L2T−1 |
| Magnetic Flux | M1 L2 T-2 I-1 |
| Magnetic field | M1 T-2 I-1 |
| Power | ML2T-3 |
| Torque | M1L2T-2 |
| Work | ML2T-2 |
| Pressure | ML-1T-2 |
| Force | M1L1T-2 |
| Surface Tension | M1L0T-2 |
