If the mass of the Earth remains the same and the radius decreases by 1%, then the value of ‘g’ at the surface of the Earth will increase by will increase by 2%. This is because gravitational acceleration ‘g’ is inversely proportional to the square of the radius, so a decrease in radius leads to an increase in ‘g’.

Option B: The value of ‘g’ at the surface of the Earth will increase by 2%. When the radius decreases by 1%, the acceleration due to gravity (g) at the surface increases because the gravitational force depends inversely on the square of the distance between two objects. Therefore, a smaller radius leads to a stronger gravitational pull, resulting in a 2% increase in ‘g’.
