## AravindG 3 years ago wel i hav some doubts on gravitation pls help

1. AravindG

Why is g maximum in Jupiter?

2. AravindG

hosein?

3. hosein

im thinking

4. AravindG

k

5. AravindG

wat i think is the jupiter is biggest planet

6. AravindG

but according that thinking g should be smallest in jupiter!!

7. AravindG

pls help

8. hosein

pls wait i should see books

9. AravindG

k

10. hosein

are you sure g is max? jupiters' r is big

11. hosein

sorry biggest not big

12. hosein

i think hence mass of it ,is very bigger than radius, g is so big i answer this by this formula$mg'=GmM/R ^{2}\rightarrow g'=GM/R ^{2}$ M=1.8986 *10^27 & R=11 * 6400 *10^3

soory so late

for more see this web http://en.wikipedia.org/wiki/Jupiter

15. AravindG

k next doubt

16. AravindG

a hole is drilled from the surface of the earth and a ball is thrown inside .the ball executes SHM why?

17. AravindG

help

18. AravindG

this is not a qn on SHM!!!

19. hosein

gravitation force couse of it $F _{gravitation}=ma$ |dw:1328451210520:dw| i will say detail... as soon as possible

The ball experiencing SMH, because once you're belong the surface of the earth, the gravitational force is directly proportional to the radial distance from the center of the earth. Hence the force the ball experiences is exactly like that it would experience on a spring.
