O' is a point on the ground chosen as origin . A body first suffers a displacement of `10sqrt(2)` mm North -East, next 10 m Noth and finally `10sqrt(2)` North-West . How far it is from origin ?

Text Solution

Verified by Experts

a) `10sqrt(2)` m North-East
b) 10 m North
`10sqrt(2)` m North-West
From figure total displacement from origin 'O' is OC
But OC = OA' + A'B' + B'C = 10 + 10 + 10 = 30 m .
