Solution
remain at the same position
The nail will remain at the same position after 3 years, but will appear to have sunk into the tree. This is because of the secondary growth of the tree which increases the girth of a tree. The increase in height of the plant will occur due to primary growth which occurs only in the regions of the apical meristems i.e. at the tips of the main stem or branches. As increase in height of the tree takes place from top only, therefore the nail will remain at the same position as it is inserted near the ground level.
