Question 4. A body makes a displacement of 4 m due East from a point O and then makes displacement of 3 m due North. Its resultant displacement from O (a) 7 m (b) 1 m (c) 5 m (d) 1 . 2 m Answer
Correct option is C) Resultant, S=3 i ^ +6 j ^ −7 i ^ =−4 i ^ +6 j ^ ∣S∣= (−4) 2 +6 2 = 16+36 = 52 m The magnitude of the resultant displacement is 52 m
