Explanation Given data: Length of three displacement vectors are 1 m , 2 m and 4 m . Explanation: Refer to Figure 1.22 in the textbook. Write the expression for net displacement of vector. d → net = d → 1 + d → 2 (1) Modify equation (1) for three displacements as follows. d → net = d → 1 + d → 2 + d → 3 Consider the different possible combination of three displacements. Consider the first combination of displacement as 1 m and 2 m are in same direction and 4 m as in opposite direction. d 1 = 1 m d 2 = 2 m d 3 = − 4 m Find the vector length. d net = 1 m + 2 m − 4 m = − 1 m Consider the second combination of displacement as 1 m and 4 m are in same direction and 2 m as in opposite direction
