The dimensional formula of surface energy is the same as that of

Options

A. surface tension
B. Spring constant
C. force gradient
D. All of these

Answer

D

Explanation

Dimension of surface energy = `[MT^(-2)]`
Dimension of surface tension = `[MT^(-2)]`
Dimension of spring constant = `[MT^(-2)]`
Dimension of force constant = `[MT^(-2)]`
