Question

A body is projected with velocity v of magnitude gR  < V < 2gR  at an angle with the radius vector of earth.  If at the highest point the speed of the   body is v/4, the maximum height attained by the body is equal to 


  1. R


Solution

The correct option is B

R


Where R = radius of earth g = 9.8 m/s2

            (Use the appropriate assumptions)

Conservation of angular momentum of the

body about 'O' yield mv (sin 30)R= mv2(R+h)

       v2R = v4(R+h)

        h =R
