Correct Answer - A `V_(0)=sqrt((GM)/(R+h))rArr V_(0)prop1/(sqrt(R+h))`
Correct option is C) A and B
Correct option is (C) 3 : 1 \(\frac{\text{Volume of cylinder}}{\text{Volume of cone}}\) \(=\frac{\pi r^2h}{\frac13\pi r^2h}\) \(=\frac31\) = 3 : 1
Correct option is (A) 1 : 3 \(\frac{\text{Volume of cone}}{\text{Volume of cylinder}}\) \(=\frac{\frac13\pi r^2h}{\pi r^2h}\) \(=\frac13\) = 1 : 3
Correct option is (B) 3 : 1 Required ratio \(=\frac{\text{Volume of cylinder}}{\text{Volume of cone}}\) \(=\frac{\pi r^2h}{\frac13\pi r^2h}=\frac31\) = 3 : 1
C) the normal force is zero
Correct Answer - A Statement 2 is the correct explanation for Statement 1.
Correct Answer - A Both the Assertion and the Reason are correct and Reason is correct explanation of Assertion.
