A person moves \(30 \mathrm{~m}\) North and then \(20 \mathrm{~m}\) towards East and finally \(30 \sqrt{2} \mathrm{~m}\) in South-West direction. The displacement of the person from the origin will be
- A \(10 \mathrm{~m}\) along North
- B \(10 \mathrm{~m}\) along South
- C \(10 \mathrm{~m}\) along West
- D zero
Answer & Solution
Correct Answer
(C) \(10 \mathrm{~m}\) along West
Step-by-step Solution
Detailed explanation
Let us use the conventional directions, as shown in figure, to solve this problem. According to question, let us draw the diagram. There are two possible diagrams. Clearly, \(\quad C E=A B=30 \mathrm{~m} \Rightarrow C D=30 \sqrt{2} \mathrm{~m}\) Using Pythagoras theorem,…
