Question

A projectile moves in a gravitational field. Which one of the following is a correct statement for the gravitational force acting on the projectile?

• A. The force is in the direction of the field
• B. The force is in the opposite direction to that of the field
• C. The force is at right angles to the field
• D. The force is at an angle between 0 and 90 to the field

Answer 1

The correct option is A The force is in the direction of the field

Projectile is mass and mass can't be negative so the force acting on it will be always along the external filed.

For example when we project a body at any angle between $0^0$ and ${90}^0$ , though it follows a parabolic path but the force acting on it always directed towards the ground that it towards the center of the earth that is towards the direction of field.

Option A is correct.
