Question

A gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body.

• A. True
• B. False

Answer 1

The correct option is A True

• The gravitational field is the actually the force experimented by a unit mass due to a body of mass M.
  
• So when a unit mass is kept at a distance 'r' from mass 'M' then it experiences a force which is equal to $\frac{GM}{r^2}$[as m=1],which is nothing but the gravitational field of mass M.
• Its units are $\frac{N}{kg}$
• Hence the above statement is true.
