Question

Solve the following problem:
The radius of planet A is half the radius of planet B. If the mass of As
M. what must be the mass of B so that the value of g on B is half that of
its value on A?
​

Answer 1

Answer:

ngmfj

$73 {5683 = \geqslant 0 { \geqslant 53 \frac{ > \geqslant \\ \times < \sqrt{ | \cot(\pi \infty \\ ) | } }{?} }^{} \: nz \: | |e \cot(x \sqrt[ \sqrt{ |84160 = = | } ]{?} ) | | 2555 = 85$

Answer 2

Answer:

2M

Explanation:

let Radius of A be R and for B will be 2R

For A: g= GM/(R)sq and For B: g/2= GX/(2R)sq

so 1/2GM/(R)sq=GX/4Rsq

giving X=2M
