Dear student
Maximum height = u² sin²theta/2g = u² /2g
Niw maximum R =u² /g
Hence maximum height = R/2

Dear student Above ans is incorrect Applying conservation of mechanical energy 1/2 mu^2 - GMm/R = - GMm/(R+h) Solving this R+h = 2gR^2 /(2gR -u^2) h = 2gR^2 /(2gR-u^2) - R h = u^2/(gR-u^2) Good Luck
