Select the correct answer. Light rays from an object after passing through a convex lens form an Image at the focal point behind the lens (opposite side of the object). What
is the actual position of the object?

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

i think the answer is a, hope this : )
