STANDARD Physics Resultant Displacement MCQ Question
A person moves 30m north, then 30m east, then 30√2m south-west. His displacement from the original position is
zero
28 m towards south
10 m towards west
15 m towards east
Correct Answer
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.
