Question : The initial and final position vectors for a particle are respectively (−3.0 m)𝐢̂+ (2.0 m) 𝐣̂+(8.0 m) 𝐤̂ and (9.0 m)𝐢̂+ (2.0 m)𝐣̂+ (−8.0 m)𝐤̂ .The displacement of the particle is

(A) (6.0 m)𝐢̂+ (4.0 m)𝐣̂+ (16.0 m)𝐤̂

(B) (6.0 m)𝐢̂

(D) (12.0 m)𝐢̂

Answer : option (C)

Solution :

The initial and final position vectors for a particle are respectively (−3.0 m)𝐢̂+ (2.0 m) 𝐣̂+(8.0 m) 𝐤̂ and (9.0 m)𝐢̂+ (2.0 m)𝐣̂+ (−8.0 m)𝐤̂ .The displacement of the particle is
