Einstein's general theory of relativity suggests that gravity is
A)a force of attraction that acts at a distance between two masses.
B)caused by curvature of spacetime.
C)= G × M₁ × M₂/d².
D)one of four fundamental forces in nature.

Question

Quizplus · Accepted Answer

In Einstein's general theory of relativity, gravity is not considered as a force that acts at a distance between two masses, but it is viewed as a result of the curvature of spacetime. This curvature is caused by the presence of massive objects which create a "depression" in spacetime that attracts other objects towards it. So, option B is the correct choice. Option A is incorrect. Option C is the equation for calculating the gravitational force between two masses, but it is not an explanation of what gravity is. Option D is partly correct, as gravity is one of the four fundamental forces in nature, but it does not provide an explanation of gravity.
