Question

If the earth shrinks to 50% of its real radius it's mass remaining the same, the weight of a body on the earth will

Answer 1

If acceleration due to gravity on earth(g) = G.M/R²,

then weight of the body = mg;

where G is gravitation constant, M is mass of earth and R is the radius.

Now if the radius is reduced by half it means g is reduces by 1/4th because it is inversely proportional to the square of radius.

And weight of the body is directly proportional to g, it will also reduce by a factor of 4.

Answer 2

Answer:

remain same

Explanation:

as the the mass of the earth remains same there the human body is not affected by the change in earth's shrinking.
