A reference frame attached to the earth

A

is an inertial frame by definition.

B

cannot be an inertial frame because the earth is revolving round the sun.

C

is an inertial frame because Newton's laws are applicable in this frame.

D

cannot be an inertial frame because the earth is rotating about its own axis.

Text Solution

Verified by Experts

The correct Answer is:
B, D
(b, d): (a) It is incorrect. Earth is an accelerated frame. Obviously it cannot be an inertial frame. (b) It is correct. (C) It is incorrect. Newton.s laws are applicable to it only as a limiting case. (d) It is correct Infact, a rotating or a revolving frame is accelerating and hence non-inertial. Options (b) and (d) are correct.
