Question

The value of 'g' at a particular point is 9.8 ms-2. Suppose the earth suddenly shrinks uniformly to half its present size without
losing any mass. The value of 'g' at the same point (assuming that the distance of the point from the centre of earth does not
shrink) will now be​

I am new please follow me friends

Answer 2

Answer:

I'm not entirely sure abt the answer, but this is my perception of it.

If you use g = GMm/d2, you'll get the value of 9.8 for the earth.

If the planet shrinks, the g is reduced to half (just find out the ratio of G1 to G2)

the answer would be 4.9 ms-2.

Again, I'm not sure so proceed at your own risk. Thanks
