Why little boy exploded 2000 feet above Hiroshima?

The atomic bomb known as "Little Boy" exploded approximately 2,000 feet above Hiroshima on August 6, 1945, to maximize its destructive power. This airburst detonation was designed to create a larger shockwave and fireball, enhancing the bomb's impact on the city and maximizing damage to buildings and infrastructure. The height of the explosion also helped to minimize the amount of radioactive fallout that would fall back onto the city, although significant radiation still affected the survivors. Ultimately, the bombing aimed to bring a swift end to World War II by forcing Japan's surrender.
