The formula to find surface tension is _______________.
Force / Length
Surface tension is the property of a liquid surface by which it behaves like a stretched elastic membrane, due to cohesive forces between its molecules.
It is defined as the force acting per unit length of an imaginary line drawn on the liquid surface: \(T = \frac{F}{L}\).
Hence its SI unit is newton per metre (N/m), and its dimensional formula is [MT⁻²].
Hence, Force / Length.
