How to find the Propotionality Constant "k"? What is the Formula for Finding it?
K is found out by performing experiment on Hook's law by applying weight and measure x in spring.
Take several readings to know accurate value of K.
The radius of a circle is proportional to its diameter. Find the constant of proportionality.
If velocity (V), force(F) and time(t) are taken to be fundamental quantities and K is the dimensionless constant of proportionality, find the dimensional formula for mass.
