Question

A javelin is thrown at an angle thita with the horizontal and range is maximum. value of tan thita is oppotion (a) 1 (b) root 3 (c) 1/root 3 (c) 2


​

Answer 1

Answer :

a) 1

Explanation:

for max range we know that the angle of projection is 45°

Tan 45 = 1

Answer 2

Answer:

a is the correct answer

WHY?

Here in the question it is mentioned that the range which means the distance traveled by the javelin is maximum .And we know that the range is max at an angle 45 degrees.which means when we throw the javelin at an angle 45 degree then it will covers the maximum range or horizontal distance

hrough which thita comes out to be 45 degrees

Although tan theta = tan 45 degree which is = 1
