NEET Physics Escape Velocity MCQ Question
Consider a diagram showing a projectile being launched vertically from the surface of the Earth. The minimum speed required for this projectile to escape Earth's gravitational influence is depicted. Which of the following expressions correctly represents this escape velocity?
(2gR_E)^0.5
(gR_E)^0.5
(GmM/R_E)^0.5
(GmM/2R_E)^0.5
Correct Answer
Detailed Explanation
The escape velocity for an object projected from the surface of the Earth is derived using the formula V = (2gR_E)^0.5, as shown in Eq. (7.32) of the NCERT context. It represents the minimum speed needed for an object to overcome Earth's gravitational pull.
