Question

dimensional formula for angle of contact

Answer 1

Angle is defined as the ratio of length of arc to radius.

Mathematically,

Angle = Length of Arc / Radius

Dimensional formula of Length = M0L1T0

Dimensional formula of Radius = M0L1T0

Substituting in the above formula we get,

Dimensional formula of Angle = M0L0T0. We can also say Angle is dimensionless quantity.

SI unit of Angle is radian (rad)
