A drone delivering medicines in a hilly terrain changes its position from A(10, 20, 30) to B(50, 40, 10) in meters. The displacement vector of the drone is: A. 40î + 20ĵ − 20k̂ B. 60î + 60ĵ + 40k̂ C. −40î − 20ĵ + 20k̂ D. 40î + 20ĵ + 20k̂ Answer: A) 40î + 20ĵ − 20k̂ Explanation: Displacement = Position B − Position A = (50−10)î + (40−20)ĵ + (10−30)k̂ = 40î + 20ĵ − 20k̂.

A drone delivering medicines in a hilly terrain changes its position from A(10, 20, 30) to B(50, 40, 10) in meters. The displacement vector of the drone is:

A. 40î + 20ĵ − 20k̂
B. 60î + 60ĵ + 40k̂
C. −40î − 20ĵ + 20k̂
D. 40î + 20ĵ + 20k̂

Answer: A) 40î + 20ĵ − 20k̂

Explanation: Displacement = Position B − Position A = (50−10)î + (40−20)ĵ + (10−30)k̂ = 40î + 20ĵ − 20k̂.
