According to Einstein, the gravity interaction is possible between
Correct answer: B. Both material objects and electromagnetic radiation
- A. Material object only
- B. Both material objects and electromagnetic radiation
- C. Electromagnetic radiations only
- D. none of these
Explanation
Reason: According to Einstein's general theory of relativity, gravity is not just a force between masses but is also the result of the curvature of spacetime caused by the presence of mass and energy, including

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.
