Question

A man walks 8 m towards East and then 6 m
towards North. His magnitude of displace-
ment is​

Answer 1

Answer:

Let the east direction to be  Î   and north direction be   j ^  .

Thus displacement of the man    S =8  Î  +6  j ^

So, magnitude of displacement  ∣  S  ∣=  6  ^2  +8 ^2  =  √  100 =10 m
