Question

A person moving on earth's surface starts from north pole and moves $500\text{k}m$ towards south and then moves $1000\text{k}m$ towards east, and then moves $500\text{k}m$ towards north and stops. The displacement of the person is :

• A. $1000\text{k}m$ eastward
• B. $\sqrt{{1000}^2+{500}^2}\text{k}m$ towards south-east
• C. $\sqrt{{1000}^2+{500}^2}\text{k}m$ towards south-west
• D. Zero

Answer 1

The correct option is D Zero


From the above diagram we can see that displacement is zero.
