Given below are two statements:

Statement (I): In projectile, if velocity of release and height of release and landing is same then range will be same if the object is released at 30° and 60°.

Statement (II): In shot-put range will be maximum when the angle of release is 45° or more than 45°.

In the light of the above statements, choose the correct answer from the options given below: 

The correct answer is Statement (I) is true but Statement (II) is false.

Explanation:

Statement (I): In projectile, if velocity of release and height of release and landing is same then range will be same if the object is released at 30° and 60°.

• If the velocity of release and the height of release and landing are the same, then the range will be the same for any angle of release that has the same vertical and horizontal components.
• This means that the range will be the same for a release angle of 30° and 60° if the initial velocity and release and landing heights are the same.

Hence Statement (I) is true.

Statement (II):  In shot-put range will be maximum when the angle of release is 45° or more than 45°.

• The optimal angle of release in shot-put is not 45° or more than 45°, but rather is closer to 42°.
• At this angle, the projectile will have the maximum range for a given initial velocity.
• If the angle of release is less than 42° or greater than 42°, then the projectile will have a shorter range due to the reduced horizontal component of its velocity.

Hence, Statement (II) is false.

Therefore, the correct answer is Statement (I) is true but Statement (II) is false.
