A particle is initially at point `A(2,4,6)m` moves finally to the point` B(3,2,-3)m`. Write the initial position vector,final position,and displacement vector of the particle.

Text Solution

Verified by Experts

Initial position vector : `vec(r )_(1)=2hat(i)+4hat(j)+6hat(k)`
Final position vector : `vec(r )_(2)=3hat(i)+2hat(j)-3hat(k)`
Displacement : `vec(d)=vec(r )_(2)-vec(r )_(1)=(3-2)hat(i)+(2-4)hat(j)+(-3-6)hat(k)`
`=hat(i)-2hat(j)-9hat(k)`
