A massless platform is kept on a light elastic spring as shown in fig. When a sand particle of mass $0.1\mathrm{kg}$ is dropped on the pan from a height of $0.24\mathrm{m},$ the particle strikes the pan and spring is compressed by $0.01\mathrm{m}$. From what height should the particle be dropped to cause a compression of 0.04m
