Question

Two vectors are given as r =2i + 3j + 5k and F=3i-2j + 4k find the resultant vector ī =r x F

Answer 1

Answer:

The resultant vector  ī =r x F is 30.

Explanation:

Here r =2i + 3j + 5k and F=3i-2j + 4k

the resultant vector ī =r x F

                              or,ī=(2i + 3j + 5k)x(3i-2j + 4k)

                              or,ī= -4+8+9+12+15-10

                               or,ī=30

so the resultant vector  ī =r x F is 30.
