Quizplus · Accepted Answer

According to the gravitational field formula, the field is directly proportional to the mass of the object and inversely proportional to the square of the distance from the object's center. Therefore, the gravitational field will be the greatest at the point closest to the center of the solid sphere, which is point 1.
