Question

If the particle moves from point p (2,3,5) to point q (3,4,5) it's displacement vector be

Answer 1

HEYA..

WE KNOW THAT DISPLACEMENT IS THE SHORTEST DISTANCE BETWEEN INTIAL [STARTING] AND FINAL POSITION...

DISPLACEMENT WILL BE-

LET STARTING POSITION VECTOR
[p] IS - 2i, 3j, 5k

where i, j and k are unit vectors

= 2i+3j+5k

AND FINAL POSITION VECTOR [q] IS - 3i, 4j, 5k

now displacement = final position -initial position

= q - p

= 3i + 4j + 5k - [2i + 3j + 5k]

= 3i - 2i + 4j - 3j +5k - 5k

= i + j

hope helped..

Here's your answer...

Let p's position vector be 2i+3j+5k.
q's position vector will be 3i+4j+5k

Displacement vector = q-p
= 3i+4j+5k-2i-3j-5k
= i+j
