Question

Question 11
A particle initially at point P(1,2,3) m moves finally to point B (3, 2, -3) m. Displacement vector of the particle is
given by -

4i + 4ј

21- 4j- 6k

21- 6k

21-4ј
explain and answer ​

Answer 1

final point : B(3,2,-3)

initial point : A(1,2,3)

displacement vector = final point vector - initial point vector

= 3i+2j-3k - i-2j-3k

=2i-6k
