A particle has di

Answer :

We first consider displacement due to 12m east and then 5 m north.

,


Let the resultant displacement be


Now,


The angle between east and north direction is 90°


So,


…1


Now the particle moves vertically upward. So, we find the resultant due to and which are at 90° to each other.


Let the total displacement be d


The, …2


Now, putting 1 in 2, we get:



Now,


So,
