Question

The proportionality constant:-
a)always has dimension
b)never has dimension
c)may have dimension
d)None of these

Answer 1

may have dimensions as many times in electrostatic law there is dimensions of its proportionality constant

Answer 2

The correct answer to the given question is option c: may have dimension.

• The proportionality constants are fixed quantities in some circumstances, as well as a ratio or combination of different quantities.
• The proportionality constants may have dimensions in certain values and are dimensionless quantities in other values.
• Proportionality constants in mathematics are usually the ratio and are dimensionless. The dimensionless quantity (Pi) is an example.
• The dimensions of a proportionality constant, such as the gravitational constant, are determined from the units of force and weight of the object in physics.
• As a result, the proportionality constant can have or not have dimensions.
