4.27 A vector has both magnitude and direction. Does it mean that anything that has
by the direction of the axis of rotation, and the angle of rotation about the axis. Does
magnitude and direction is necessarily a vector ? The rotation of a body can be specified
that make any rotation a vector ?
Answers
Answer:
No. A physical quantity having both magnitude and direction need not be considered a vector. For example, current having magnitude and direction, current is a scalar quantity. The essential requirement for a physical quantity to be considered a vector is that it should follow the law of vector addition.
Generally speaking, the rotation of a body about an axis is not a vector quantity as it does not follow the law of vector addition. However, rotation by a certain small angle follows the law of vector addition and is therefore considered a vector.

hope it helps.. pls thanks mr and mark me brainliest plsssss
Answer:
no!! vector means it has magnitude as well as direction but it's treats with help of vector rule( parallelogram rule) not with help of simple algebraic rule... the finite rotation of a body about an axis isn't vector even though has magnitude as well as direction because it doesn't obey vector rule for addition.

I hope that this answer Will help you. thank you
