JEE Main 29 July 2022, Shift 1, Physics Q51

Question 51 of 90 in this shift, Physics question 21 of 30, Section B.

An object is projected in the air with initial velocity u at an angle θ\theta. The projectile motion is such that the horizontal range R, is maximum. Another object is projected in the air with a horizontal range half of the range of first object. The initial velocity remains same in both the case. The value of the angle of projection, at which the second object is projected, will be __________ degree.
