Correct option: (a, c)
Explanation:
is a meaningful operation.
Therefore, (a) is the answer.
is not meaningful since vector(v . w), is a scalar quantity and for dot product both quantities should be vector.
Therefore, (b) is not the answer.
is meaningful, since it is a simple multiplication of vector and scalar quantity.
Therefore, (c) is the answer.
is not meaningful since vector(v . w) is a scalar quantity and for cross product, both quantities should be vector.
Therefore, (d) is not the answer.
