Question

what will be the effect on the weight of a body if the average density of earth is same and diameter reduces to half of the present value​

Answer 1

Explanation:

then

the weight will become 4 times when the diameter of the earth is halved.

Answer 2

Answer:

looking at Newton’s equation for universal gravitation we can see that the force of gravity is inversely proportional to the square of the distance between them.

F=G*(m1*m2/r^2)

where F is the gravitational force acting between two objects and r is the distance between the centers of their masses.

In this case the distance between the center of a body mass and Earth’s mass is halved, which gives us a force 4 times stronger than it was. You’d have quite a bit of trouble standing up as you would weigh 4 times as much.
