Question

A body weighs 200 n on the surface of the earth .How much will it weighs half way down to the centre of the earth

Answer 1

Answer:

20

Explanation:

w=mg

w=200n

g=10m/s^2

m=w/g=200/5=40n

as half way to center of earth decreases half of gravitational force

hope you help it

Answer 2

Answer:

100N

Expaccoding to this the acceleration due to gravity depth is Dfrom earth so, g'=g[1-d/r] ,   mg'=mgl1-d/r]  , 200[1-r/2r]  here we know [d= r/2]  200/2=100
