A particle is projected from ground at an angle `theta` with horizontal with speed u. The ratio of radius of curvature of its trajectory at point of projection to radius of curvature at maximum height is -

A particle is projected with speed u at angle theta to the horizontal. Find the radius of curvature at highest point of its trajectory

A particle is projected with speed u at angle theta to the horizontal. Find the radius of curvature at highest point of its trajectory

A projectile is projected at a angle 60^(@) with horozontal with speed 10 m/s. The minimum radius of curvature of the trajectory described by the projectile is

A particle is projected with a speed u at an angle theta with the horizontal . If R_(1) is radius of curvature of trajectory at the initial point and R_(2) is the radius of curvature at the highest point . Value of R_2//(R_(1) is found to be cos ^(n) theta . What is the value of n ?
