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
Anonymous:
2i - 6k
how
displacement = position vector of B - position vector of A
thank u so much
so d = 3i + 2j - 3k - (i + 2j - 3k)
= 2i + 6k :)

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
