Passage III A block of mass m =1/2 kg is attached with two springs each of force contant k=10N/m as shown. The block is oscillating vertically up and down with amplitude A=25cm. When the block is at its mean position one of the spring breaks without changing momentum of block.

If instead of breaking one spring m/2 mass would have fallen from the block, then what will be the new amplitude?

A

21.6cm

B

26.2 cm

C

15.8 cm

D

16.9 cm
