Question

what are dimension of plane angle​

Answer 1

Answer: it is dimensionless

Explanation:

As we know that angle = length/radius

So it is m/m

Which is equals to zero

so it is dimensionless

Answer 2

The dimensions of the Plane Angle are [M⁰ L⁰ T⁰].

→ The value of the Plane Angle is given by the Arc length divided by the radius.

                                   $Plane Angle = \frac{Arc Length}{Radius}$

→ As the Plane Angle is a ratio of two similar quantities that is the Arc length and the radius both having dimensions equal to [M⁰ L¹ T⁰]. Hence the Plane Angle is a dimensionless quantity.

Therefore, the dimensions of the Plane Angle are [M⁰ L⁰ T⁰].
