General Science - Physics MCQs

Q.  Who gave the Theory of Relativity?

a. Isaac Newton
b. Archimedes
c. Albert Einstein
d. Galileo Galilei


ANSWER: See Answer
 
Albert Einstein was the founder of Theory of Relativity. According to Einstein’s theory, mass m is equivalent to energy E given by the relation E = mc^2 where c is speed of light in vacuum. Albert Einstein was awarded the 1921 Nobel Prize in Physics for his contribution to the field of Theoretical Physics.
