Assertion (A) : The Laws of Physics, all take the same identical form for all frames of reference in uniform relative motion (for all inertial frame of references)
Reason (R) : This is due to absence of an absolute or fixed frame of reference.
In the light of the above statements, choose the most appropriate answer from the options given below :
Analysis of Assertion (A)
Assertion (A) states that the laws of physics have the same form in all inertial frames of reference (frames in uniform relative motion). This is a fundamental principle in physics, known as the principle of relativity. It is a correct statement.
Analysis of Reason (R)
Reason (R) explains that the reason behind the identical form of physics laws in all inertial frames is the absence of an absolute or fixed frame of reference. This concept, that all inertial frames are equivalent and there's no preferred stationary frame, is also a cornerstone of both classical mechanics (Galilean relativity) and special relativity.
Relationship between Assertion and Reason
The reason (R) directly explains why the assertion (A) is true. If there is no absolute frame of reference, then all inertial frames must be equivalent, leading to the laws of physics taking the same form in each.
Conclusion
Both Assertion (A) and Reason (R) are correct statements, and Reason (R) provides the correct explanation for Assertion (A).
Selected Option
Therefore, the most appropriate answer is Option 1: Both (A) and (R) are correct and (R) is the correct explanation of (A).
