A) \[10\text{ }m\]along north
B) \[10\text{ }m\]along south
C) \[10\text{ }m\] along west
D) zero
Correct Answer: C
Solution :
Taking the starting point as O, we have \[30\text{ }m\] north OA, \[20\text{ }m\]east AB, and finally \[30\sqrt{2}m\] \[(S-E)\] BD. From \[\Delta CAB,\] \[AC=20m,\text{ }OC=10m\] In \[\Delta OCD,\] \[OD=OC,\text{ }OD=10m\] Hence, final displacement from origin is 10 m.You need to login to perform this action.
