Question

When the range of a projectile on an inclined plane is maximum then:

• A. The focus of the path is on the plane
• B. The focus of the path is below the plane
• C. The focus of the path is above the plane
• D. The focus of the path lies at any place

Answer 1

The correct option is A The focus of the path is on the plane

When the range of the projectile becomes maximum then the parabolic trajectory has its focus on the inclined plane only. So answer should be option A only.
