A block is suspended by a spring and the deflection produced in the spring is $$2$$ cm when the block is slightly pulled downward and released, its time period is found to be $$1$$ second. When another block is suspended by the same spring, its elongation is found to be $$8$$ cm. Now if this block is slightly pulled downward and released, what will be its time period?
