A projectile is fired from the surface of earth of radius R with a velocity `etav_(e)` where `v_(e)` is the escape velocity and `eta lt 1`. Neglecting air resistance, the orbital velocity of projectile is -

A projectile is fired from the surface of earth of radius R with a velocity k upsilon_(e) (where upsilon_(e) is the escape velocity from surface of earth and k lt 1) . Neglecting air resistance, the maximum height of rise from centre of earth is

A projectile is fired from the surface of earth of radius R with a velocity k upsilon_(e) (where upsilon_(e) is the escape velocity from surface of earth and k lt 1) . Neglecting air resistance, the maximum height of rise from centre of earth is

A particles is fired vertically from the surface of the earth with a velocity Kv_(e) , where u_(e) is the escape velcocity ans Klt 1 . Neglecting air resistance , calcualte the heightto which it will rise from the surface of the earth .(R= radius of the earth ).

A projectile is fired vertically upward from the surface of earth with a velocity Kupsilon_e where upsilon_e is the escape velocity and K lt 1. Neglecting air resistance, show that the maximum height to which it will rise measured from the centre of earth is R/(1-K^2) where R is the radius of the earth.
