Question

A PLANET HAS DENSITY P , RADIUS R AND ACCELERATION DUE TO GRAVITY AS g . IF THE RADIUS OF THE PLANET WERE DOUBLED , KEEPING THE DENSITY SAME , THE ACCELERATION DUE TO GRAVITY AT THE SURFACE WILL BE

Answer 1

Please refer the above photograph for the used process.
g will decrease
If correct plz mark as branliest.

Answer 2

Answer: 2g

Explanation: here- density(d), radius(R)

By using the formula in gravitation,

g = G.d.4/3π.r

Given, radius is doubled then,

g = G.d.4/3π.2r

=2(G.d.4/3π.r)

Therefore, g = G.d.4/3π.r

= 2×g

= 2g
