the initial and final and posdition vector for a particle are(-3) `hati+(2m)hatj+(8m)hatk `and `(9m)hati+(2m) hatj+(-8m)hatk` respectively ,find the displacement of the particle.

Text Solution

Verified by Experts

Displacement of particle =final- Initial position
`=[(9m)hati+(2m)hatj+(-8m)hatk]-[(-3m)hati+(2m)hatj+(8m)hatk]`
`=(12m)hati+(-16)hatk`
