Question

The ratio of height of a man to the radius of the earth is of the order

Answer 1

Radius of earth = R

density of earth = p

acceleration due to gravity = g = GM/ R²

M= 4/3 λ R³p

so, g = 4/3G λ Rp

acceleration due to gravity on planet

g' = G'M'/ R'²

or g' = 4/3 G'λR'p'

p' = 1/4p

R' = 1/3 R

g' = 1/12(4/3 GλRp)

g' = 1/12g

the height through which a man can jump on the planet = h'

g/g' = h/h'

12= h'/ 1.5

h'= 18m
