Answer 1

hey mate !!!

as per the condition, the particle moves 3m in x direction, 4m in the y direction and 5m in the z direction.

the the movement of the particle in the vectors term can be written as

3i + 4j + 5k

thus, the net displacement is

√(3^2 + 4^2 + 5^2)

= √(9+8+25)

=√(50)

=7.07

thus the net displacement is 7.07 units in the direction of vector

3i + 4j + 5k

hope you've found it informative !!!
