Question 23
The first diagram shows the force of gravity (F) between two objects separated by some distance (d).
What is the force of gravity in the second diagram?
A. 1/2 F
B. F
C. 2F
D. 4F

Answer

Answer: The force of gravity between two objects is given by Newton's law of universal gravitation: F = G * (m1 * m2) / d^2. In the second diagram, the distance is halved (d/2), so the force becomes F' = G * (m1 * m2) / (d/2)^2 = 4 * G * (m1 * m2) / d^2 = 4F. Therefore, the correct answer is D. 4F.
