Statement-I: If

\vec{a} \cdot \vec{b}=\vec{b} \cdot \vec{c}

, then

\vec{a}

may not always be equal to

\vec{{c}}

.
Statement-II: The dot product of two vectors involves cosine of the angle between the two vectors.

View answer and explanation

Correct option: A

Statement-I is true and statement-II is true

Statement-I is true because the dot product does not imply equality of vectors. Statement-II is true because the dot product is defined using the cosine of the angle between the vectors.
