Explanation:
Dimensions in physics refer to the physical quantities such as length, mass, time, etc., which are used to describe the nature of a quantity. Dimensions are often represented by symbols like [M] for mass, [L] for length, and [T] for time.
Check dimensional correctness of a formula:
- Dimensions are crucial for checking the dimensional correctness of a formula. By ensuring that the dimensions of the quantities on both sides of an equation match, one can verify the validity of the formula.
Convert units:
- Dimensions play a key role in unit conversions. By using dimensional analysis, one can convert units from one system to another by manipulating the dimensions of the quantities involved.
Find value of the constant of proportionality in an equation:
- Dimensions cannot be used to find the value of the constant of proportionality in an equation. The constant of proportionality is a dimensionless quantity that relates two directly proportional physical quantities. It is determined experimentally, not through dimensional analysis.
Deduce a relation among physical quantities:
- Dimensions can be used to deduce relations among physical quantities. By analyzing the dimensions of various quantities in an equation, one can derive relationships that help in understanding the underlying physics.
Therefore, the correct answer to the question is option C: Dimensions cannot be used to find the value of the constant of proportionality in an equation.
