Question

Three projectiles A, B and C are projected at an angle of 30°, 45°, 60° respectively. If RA, RB and RC are ranges of A, B and C respectively, then (velocity of projection is same for A, B and C) 

(1) R_A = R_C > R_B 

(2) R_A = R_C < R_B 

(3) R_A = R_B = R_C 

(4) R_A < R_B < R_C

Answer 1

Correct option (2) R_A = R_C < R_B

Explanation:

Range is maximum for 45°

∴ B has maximum range

Range is same for both 30° and 60° as they are complementary angles.

∴ R_A = R_C < R_B
