Question

Distinguish between scalar and vector
Product also

find p+Q if p=2i+3j-k and Q=2i-5j +2k
​

Answer 1

Explanation:

If the product of two vectors is a scalar quantity, the product is called a scalar product or dot product. If the product of two vectors is a vector quantity then the product is called vector product or cross product. If two vectors are perpendicular to each other then their scalar product is zero
