According to the Universal Law of Gravitation, the force of attraction between two bodies is inversely proportional to: MCQ with Answer and Explanation

According to the Universal Law of Gravitation, the force of attraction between two bodies is inversely proportional to:
A. The square of the distance between their centers.
B. The distance between them.
C. The sum of their masses.
D. The product of their masses.
Answer: Option A
Solution (By JKExamLibrary)
Newton's Law of Universal Gravitation states that the gravitational force (F) between two point masses is directly proportional to the product of their masses (m1 × m2) and inversely proportional to the square of the distance (r²) between their centers. The mathematical formula is F = G(m1m2)/r².

Question #3
A block of mass 10 kg is accelerating at 2 m/s^2 on a horizontal surface under an applied force of 50 N. What is the magnitude of the frictional force opposing its motion?
A. 50 N
B. 20 N
C. 30 N
D. 70 N

Correct Answer: Option C


Explanation:
According to Newton's Second Law, the net force on the block is F_net = mass * acceleration = 10 kg * 2 m/s^2 = 20 N. The net force is the difference between the applied forward force and the opposing frictional force (F_net = F_applied - F_friction). So, 20 N = 50 N - F_friction. Solving for friction gives F_friction = 50 - 20 = 30 N.
