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 incrtial frame because Newton's laws are applicable in this frame

D

cannot be an incrtical frame because the Earth is rotating about its own axis

Text Solution

Verified by Experts

The correct Answer is:
b,c
Option `a` is wrong since earth is an acceleration and hence cannot be as inetial force
option `b` is correct
option `c` is uncorrect stricly speaking as earth is acceleration referance fram (earth is treated as a reference force for praticaly exeples and newton 's lows are applicable toa only as a limiting (d) is correct

    B
    If both Assertion & Reason are True but Reason is not a correct explanation of the Assertiion.
    C
    If Assertion is True but the Reason is False.
