Question

Range of projectile is R,when angle of projectile is 30°. Then the value of the other angle of projectile for the same range is​

Answer 1

Answer:

60°

Solution:-

If two bodies thrown at same speed at angles such that their sum =/2 then both of them will have the same range.

(Because due to this value of sin$(2\theta)$ will not change.)

so the other angle has to be

90 –30=60°

Answer 2

$\huge\underline{\pink{A}\orange{N}\blue{S}\purple{W}\red{E}\orange{R}}$

60°

Solution:-

If two bodies thrown at same speed at angles such that their sum =/2 then both of them will have the same range.

(Because due to this value of sin(2\theta)(2θ) will not change.)

so the other angle has to be

90 –30=60°
