A body is projected vertically upwards with a speed of √GMR. The body will attain a height of
(M is mass and R is Radius of earth)
Key Concept - The gravitational potential energy for 2 point masses is given by U=−Gm1m2/r Why this question? Note - A uniform spherical mass can be considered to be a point mass concentrated at its center to calculate gravitational potential energy, if the other mass is outside the sphere. |
