हिन्दीThree identical point masses, each of mass \( m \), are placed at the vertices of an equilateral triangle of side length \( 1\text{ m} \). A point mass \( 2m \) is placed at the centroid of the triangle. What is the net gravitational force experienced by the mass at the centroid?
Correct answer · Option 1
Zero
Explanation
By symmetry, the three equal gravitational forces from identical masses at equal distances are separated by 120 degrees, so their vector sum is zero.
