According to Einstein, mass and energy are:
- A
Inversely proportional
- B
Directly proportional
- C
Equal to each other
- D
None of these options is correct
Option A) Inversely proportional is not correct because the relationship between mass and energy is a direct proportion, as described by the equation E=mc².
Option B) Einstein's equation, E = mc2, shows that mass and energy are interchangeable and are directly related. It states that mass is concentrated energy.
Option C) Equal to each other is not correct because mass and energy are not equal in value, but rather are related by a proportionality constant (the speed of light squared).
Option D) None of these options is correct is not correct because the correct answer is B) Directly proportional.
