Mass of a body is 25 kg. What is its weight in Newton on earth? The body is carried to a planet whose mass is two times the mass of earth and radius is half that of earth. What will be the mass and weight of the body on the planet? (Take the value of g on earth as 10 m s–2) please answer fast

Weight is given by
Mass*Accleration due to gravity
= 25*10
=250 Newton
Let's find the acceleration due to gravity on that planet,
g=GM÷r^2(Where,G=gravitional constant and r=radius of planet,M=mass of planet)
g'=G*2M÷r/2^2
g'=G*4M/r^2
so, g'=4g
so g on that planet will be 10*4=40 m/s
weight of person on that planet=25*40
= 1000 Newton
