							since a body is projected with velocity u at angle theta.consider it a tangential velocity of a body in a circular arc  .now,      gcos(theta)=u2/r. find r.                                                                                                 

u2=square of u
gcos(theta)=component of g along the radius(perpendicular to tangent)
