Answer:
Correct Answer: 57.(b)
Solution:
In all the given four figures, at mean position, the position coordinate is zero. At the same time, mass is starting from the extreme position in all four cases. In Fig. (c) and (d), extreme position is more than the initial extreme position. But due to viscosity, the position should be less. Hence, the answer should be either option (a) or option (b). Correct answer is (b), because the mass starts from the positive extreme position (from uppermost position). Then, it will move downwards, and momentum should be negative.
