    				| 1. | A particle can move only along x-axis. Three pairs of initial and final positions of particle at two successive times are given Pair Initial positions Final position 1 (-3)m (+5)m 2 (-3) m (-7)m 3 (+7) (-3), Find the sum of magnitudes of displacement in the pairs which give negative displacement in m. | 
| Answer» Correct Answer - 14 `s_1 = 5(-3) = 8m` `s_2 = -7-(-3) = -4m` `s_3 = -3-7 = -10m` Required value = `(s_2+s_3) = (-14) = 14`. | |
