1. Bring the magnets together in T formation, if the magnet is the horizontal bar (the top ot T), it will try to align the iron bar according to its magnetic lines of attraction, which run parallel to its body. Hence the iron bar will tend to incline. What will happen in the other case?
2. Plant three trees in an equilateral triangular formation. For the fourth one, either dig a hole at the centroid of the triangle, or pile up that point with sand, so that the height (or depth) is such that the distance of this point from any triangle vertex is equal to the side of the triangle. Can you find this value of height?
3. Migratory birds don't come to India in summers.
