Question

if vector a=3 unit due east and vector b=4 unit due 60 degree north of west find resultant​

Answer 1

Answer:

f resultant of 4,3 vectors is 1. Then it simply means 4 and 3 are place opposite in direction or angle between then is π radians.

Cross product is all about sin of angle between two vectors.

So sin π=0

So cross product is zero.

See that there is no big calculation involved here.

Explanation:

Answer 2

Let, vector a=3 ;

vector b=4 ;
