Question

DATE :
Find position vector blw points (3, 2, -1) & (5,-1,-2)
(b) magnitude & unit vector of Position vector.​

Answer 1

Answer:

uder root 22 2i^-3j^-3k^

Explanation:

position vector between two points is given by

(x2-x1)i^+(y2-y1)j^+(z2-z1)z^

and magnitude given by under root

(x2-x1)^2 + (y2-y1) ^2 + (z2-z1)^2

i^ means i cap

i hope you understood
