NEET Physics (general) MCQ Question
Consider a sphere of uniform density with a radius r. Point P is located outside this sphere at a distance r from the center. Describe the gravitational force experienced by a mass m placed at point P. Which of the following best represents the scenario described?
The sphere exerts no gravitational force on mass m at P.
The gravitational force on mass m is as if the entire mass of the sphere is concentrated at its center.
The gravitational force on mass m is zero because P is outside the sphere.
The gravitational force on mass m is inversely proportional to the square of the distance from the sphere's surface.
Correct Answer
Detailed Explanation
According to the NCERT context, for a point P outside a sphere of uniform density, the gravitational force is as if the sphere's mass is concentrated at its center.
