Question

Vertical limit of contrast astronaut can jump on the earth is 0.5 meters find the maximum vertical distance through which we can someone the moon which has a mean density two third of the earth and radius one fourth of the earth

Answer 1

3m,6:1

6m,3:1

3m,1:6

6m,1:6

Answer :

A

Solution :

g'= acceleration due to gravity on the Moon

=G43πR'ρ'=G43π×R4×23ρ=g6

Now hm=u22g or hm∝18

Hence h′mg'=hmg

or h′m=6hm=6×0.5=3m

ii. f=2ug or t∝1g

t'g'=tg or t't=gg'=61
