A solid sphere of mass M and radius R is surrounded by a spherical shell of same mass and radius 2R as shown. A small particle of mass m is relased from rest from a height h`(lt lt R)` above the shell. There is a hole in the shell. Q. With what approximate speed will it collide at B?A. `sqrt((2GM)/(R))`B. `sqrt((GM)/(2R))`C. `sqrt((3GM)/(2R))`D. `sqrt((GM)/(R))` |

Answer» Correct Answer - D COME `implies0-(G(2M)m)/((2R+h))=(1)/(2)mv^(2)-(GMm)/(R)-(GMm)/(2R)` `impliesvcongsqrt((GM)/(R))` |
