Question

what is the dot product of two vectors of magnitude 3 and 5 if angle between them is 60° ​

Answer 1

Answer:

7.5

Explanation:

The scalar product (dot) of two vectors is define as the product of their magnitude with cosine angle between them..

here A=3andB=5...cos60=1/2

..A. B=3.5.1/2

À. B=7.5......hope you understand... then follow me
