Assertion : In javelin throw, the athlete throws the projectile at an angle slightly more than `45^(@)`.
Reason : The maximum range does not depends upon angle of projection.

The range of a projectile at an angle theta is equal to half of the maximum range if thrown at the same speed. The angel of projection theta is given by

The angle of banking of the road does not depend upon

Show that the horizontal range of a projectile is same for two angles of projection . Is the sum of maximum heights for these two angles dependent on the angle of projectile ?

The question given below consist of an assertion and the reason . Use the following key to choose appropriate answer: Assertion: Range of projectile motion is same when particle is projected at an angle theta with the horizontal or at an angle (90^(@) -theta) with the horizontal . Reason : Range of projectile motion depended only on the angle of projection.

Assertion: Horizontal range is same for angle of projection theta and (90^(@)- theta) . Reason : Horizontal range is independent of angle of projection.

The range of a projectile is R when the angle of projection is 40^(@) . For the same velocity of projection and range, the other possible angle of projection is

Show that the horizontal range is maximum when the angle of projection is 45^(@)

Assertion (A) : Alkylated mercury is more toxic than mercury. Reason (R) : The toxicity of the pollutant depends upon the nature of speciation.

Assertion: For projection angle tan^(-1)(4) , the horizontal range and the maximum height of a projectile are equal. Reason: The maximum range of projectile is directely proportional to square of velocity and inversely proportional to acceleration due to gravity.
