A) 10 m along north
B) 10 m along south
C) 10 m along west
D) zero
Correct Answer: C
Solution :
Taking the starting point as 0, we have 30 m north OA, 20 m east AB, and finally\[30\sqrt{2}\text{ }m\] \[(S-E)BD\]. From\[\Delta CAB,\] \[AC=20\text{ }m,\text{ }OC=10\text{ }m\] In\[\Delta OCD,\] \[OD=OC,\text{ }OD=10m\] Hence, final displacement from origin is 10 m.You need to login to perform this action.
