Laws Of Motion Question 27
Question: Assertion: A reference frame attached to earth is an inertial frame of reference. Reason: The reference frame which has zero acceleration is called a non-inertial frame of reference.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.

Answer:
Correct Answer: D
Solution:
An inertial frame of reference is one which has zero acceleration and in which law of inertia hold good i.e. Newton’s law of motion are applicable equally. Since earth is revolving around the sun and earth is rotating about its own axis also, the forces are acting on the earth and hence there will be acceleration of earth due to these factors. That is why earth cannot be taken as inertial frame of reference.
