Which of the following is a property of a uniform gravitational field?
Correct answer: D. Its field strength is the same at all points within it
- A. Its magnitude is the same in all directions
- B. The gravitational potential has the same value at all points within it
- C. Its direction is opposite to the direction of motion of attest mass released in it
- D. Its field strength is the same at all points within it
Explanation
d) Its field strength is the same at all points within it:This option suggests that the field strength (magnitude of the gravitational field) is the same at all points within a uniform gravitational field. This is correct. In a uniform gravitational field, the field strength is constant throughout the field. The field strength determines the magnitude of the gravitational force experienced by an object in the field.

About Law of Universal Gravitation
Every two masses attract each other with a force proportional to the product of their masses and inversely proportional to the square of their separation, expressed as F = Gm₁m₂/r². Questions also involve the gravitational constant, vector direction, superposition of gravitational forces, and the distinction between gravitational force and gravitational field strength.
