When a mass is rotating in a plane about a fixed point, its angular momentum is directed along.

Options

A. A line perpendicular to the plane of rotation
B. The line making an angle of `45^(@)` to the plane of rotation
C. The radius
D. The tangent to the orbit

Answer

A

Explanation

We know that `bar(L) = m(bar(r )xxbar(v))` So here , angular momentum is directed along a line perpendicular to the plane or rotation .
