A particle moves 4 km North East and reach position A and then moves 3 Km South East to reach the position B. Let assume the initial point has co-ordinates (0, 0). Co-ordinates of the position A and B are (xa, ya) & (xb,yb).Also i and j are the unit vector across the x and y direction Find out the following:
a.Find out the co-ordinates of Position A and B
b.Find out the distance of point B from the Origin
c.Find out the position vector of point A and B
