Magnitude of Resultant Displacement
A particle undergoes two successive displacements, given by r₁ = (3î + 4ĵ) m and r₂ = (−2î + 5ĵ) m. Which of the following expressions represents the magnitude of the particle’s total displacement?
A
√(1² + 9²) m = 9.1 m
B
√(3² + 4²) + √(2² + 5²) m = 10 m
C
√(1² + 9²) m = √82 m
D
√((3 - 2)² + (4 + 5)²) m = √82 m
