Text Solution
Verified by ExpertsThe correct answer is:
D
We know that,
escape velocity from earth's surface, 
Also, Density 
Mass 
Density 
Volume or 
or 
Substituting the values in the escape velocity expression, we get
… (i)
Given, radius of another planet is 4 times the radius of the earth,
On dividing Eq. (ii) by Eq. (i), we get
