1.	In the figure shown a block of masss `m` is atteched at ends of two spring The other ends of the spring are fixed The mass `m` is released in the vertical plane when the spring are released The velocity of the block is maximum when A. `k_(1)` is compressed and `k_(2)` is elongatedB. `k_(1)` is elongated and `k_(2)` is compressedC. `k_(1)` and `k_(2)` both are compressedD. `k_(1)` and `k_(2)` both are elongated.
Answer» Correct Answer - B Speed of block is maximum at mean position. As mean position upper spring is extended and lower spring is compressed.
