STANDARD Physics Resultant Displacement MCQ Question
Type: MCQ-conceptual-Medium
A person moves 30m north, then 30m east, then 30√2m south-west. His displacement from the original position is
A
zero
B
28 m towards south
C
10 m towards west
D
15 m towards east
Correct Answer
Option A
Detailed Explanation
Resolving the displacement 30√2m south-west into two rectangular components, we find that both components are 30m. The effective displacement due to 30m north and 30m south is zero, and the effective displacement due to 30m east and 30m west is zero.
