if the earth shrinks thus decreasing its radius the value of g at its surface will
​

Answer 1

Answer: Acceleration due to gravity at earth's surface g=

Acceleration due to gravity at earth's surface g= R

Acceleration due to gravity at earth's surface g= R 2

Acceleration due to gravity at earth's surface g= R 2

Acceleration due to gravity at earth's surface g= R 2 GM

Acceleration due to gravity at earth's surface g= R 2 GM

Acceleration due to gravity at earth's surface g= R 2 GM

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.⟹ g∝

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.⟹ g∝ R

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.⟹ g∝ R 2

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.⟹ g∝ R 2

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.⟹ g∝ R 2 1

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.⟹ g∝ R 2 1

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.⟹ g∝ R 2 1 (for constant M)

Acceleration due to gravity at earth's surface g= R 2 GM where M and R is the mass and radius of earth, respectively.⟹ g∝ R 2 1 (for constant M)Hence acceleration due to gravity increases as the radius of earth decreases (i.e if earth shrinks).
