If density of earth increased times and its radius became half of what it is, our weight will
be doubled
Step 1: Given data
The density of the earth increased times
Radius became half
We have to find the change in our weight
Step 2: Formula used
We know,
Weight,
Where
our mass
mass of earth
acceleration due to gravity
gravitational constant
radius of earth
volume of earth
density of earth
Step 3: Calculating weight
Initial weight,
Final weight,
Therefore, the weight will be doubled
Hence, option B is correct.
