Chapter 9: Q. 40 (page 627)

In Problem, use the given vectors u, v, and w to find the given expression.

w脳w脳vu=2i-3j+kv=-3i+3j+2kw=i+j+3k

Short Answer

Expert verified

The resultant of the given equation is : 0

Step by step solution

01

Step1. Given information

vectorsu=2i-3j+kv=-3i+3j+2kw=i+j+3k

equation:W脳W脳V

02

Step2. calculating the equation 

We know that

x=ai+bj+cky=pi+qj+rkx脳y=ijkabcpqr

so according to question

w脳w=ijk113113=i1313-j1313+k1111w脳w=0w脳w脳v=0脳v=0
