Two persons just manage to push a block from left to right direction along a horizontal level road with uniform velocity. When the same block is pushed by three people in same direction a constant acceleration of 0.2m\s*s is produced in the block . If the five person push the block in same direction together, then the magnitude of acceleration of the block will be (assume that each person applies the force equal in magnitude)
(1) 0.4m/s*s
(2) 0.6m/s*s
(3) 0.8m/s*s
(4) 1m/s*s
