Physics-Universal Law of Gravitation
NEET Physics Universal Law of Gravitation MCQ Question
Type: MCQ-numerical-Medium-Class 11
If two point masses, each of mass 5 kg, are separated by a distance of 10 meters, what is the magnitude of the gravitational force between them? (Use G = 6.672×10⁻¹¹ N m² kg⁻²)
A
67 × 10⁻¹¹ N
B
34 × 10⁻¹¹ N
C
6.67 × 10⁻¹² N
D
34 × 10⁻¹² N
Correct Answer
Option A
Detailed Explanation
Using Newton's law of universal gravitation, F = G * (m₁ * m₂) / r² = 6.672×10⁻¹¹ * (5 * 5) / (10)² results in a force of 1.67 × 10⁻¹¹ N.
