Question
A reference frame attached to the earth
Options
A.is an inertial frame by definition
B.cannot be an inertial frame because the earth is revolving around 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 axis.
Solution
(B,D)
A non-accelerated frame is defined as inertial frame.
Due to revolution of earth around sun it is accelerated towards the sun. Hence frame of option (B) is not an inertial frame.
Again due to rotation of earth about its axis a frame of option (D) is also an accelerated frame that is why it cannot be considered an inertial frame.
