Which of the following is the cause of tides ?
A. Moon's gravitational pull
B. Sun's gravitational pull
C. Centrifugal force
D. Gravitational pull of Earth
Answer and explanation
Correct answer A
A, B and C give the conventional textbook explanation, (1): lunar and solar attraction together with the centrifugal description in the rotating Earth–Moon frame. Physically the tide-generating effect is a differential acceleration across Earth; the frame-dependent centrifugal term is not a third independent external gravitational source.
