If the earth shrinks in its size (radius) mass remaining the same, the value of g on its surface will

Options

  1. Aincrease
  2. Bdecrease
  3. Cremains same
  4. Dreduce to zero

Correct answer

A. increase

Step-by-step solution

The acceleration due to gravity at earth's surface is given by g= G M R² As, mass remains constant. g 1 R² so, as the radius of earth decreases or the earth shrinks in size, the value of g increases.
