359996 One can easily weigh the earth by calculating the mass of earth by using formula

359997 For a body projected at an angle with the horizontal from the ground, choose the correct statement.

359998 If there was a reduction in gravitational effect, then which of the following forces do you think would change in some respect?

359999 A projectile of mass \({m}\) is fired from the surface of earth at an angle \({\alpha=60^{\circ}}\) from the vertical. The initial speed of the projectile is \({u=\sqrt{\dfrac{G M}{R}}}\), where \({M}\) and \({R}\) are mass and radius of the earth. Find the height by the projectile in kilometer. Neglect air resistance and the rotation of earth. (Given \({R=6400 {~km}}\))
