Question

If the angular displacement is large, it is a scalar quantity because ______.

Options

• its magnitude for large values cannot be calculated.

• it is not coplanar for large values.

• it will not obey the commutative law of vector addition.

• it will not obey principle of homogeneity.

Answer 1

If the angular displacement is large, it is a scalar quantity because it will not obey the commutative law of vector addition.

Explanation:

Large angular displacements are scalar because rotating an object by two large angles in different sequences gives different final positions, proving they do not follow the commutative law of vector addition.
