A particle is projected vertically upward from the surface of
the earth with a speed of [IMAGE], R being the radius
of the earth and g is the acceleration due to gravity on the surface of
the earth. Then the maximum height ascended is nR,then value of n
is(neglect cosmic dust resistance)

Show answer and solution

[IMAGE] and g = [IMAGE] Therefore [IMAGE] ×[IMAGE] × gR - Rg =
- [IMAGE] We get h = 3R
