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.
✓

Answer

(d) An inertial frame of reference is one which has zero acceleration and inwhichlawofinertia 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 whyearthcannotbetaken as inertial frame of reference.
