JEE MainPhysicsMotion in A PlaneMCQ+4 / −1
A balloon is moving up in air vertically above a point A on the ground. When it is at a height h1, a girl standing at a distanced (point B) from A (see figure) sees it at an angle 45o with respect to the vertical. When the balloon climbs up a further height h2, it is seen at an angle 60o with respect to the vertical if the girl moves further by a distance 2.464 d(point C). Then the height h2 is (given tan 30o = 0.5774) JEE Main 2020 (Online) 5th September Morning Slot Physics - Motion in a Plane Question 61 English
