Kinematics Question 124
Question: Position of a particle in a rectangular-co-ordinate systeM is (3, 2, 5). Then it’s position vector will be
Options:
A) $ 3\hat{i}+5\hat{j}+2\hat{k} $
B) $ 3\hat{i}+2\hat{j}+5\hat{k} $
C) $ 5\hat{i}+3\hat{j}+2\hat{k} $
D) None of these
Correct Answer: B If a point have coordinate (x, y, z) then it’s position vector $ =x\hat{i}+y\hat{j}+z\hat{k}. $
