If Newton's law of universal gravitation turned out to be Gm1m2/r rather than Gm1m2/r2, tides on Earth
A. would not happen because the force of gravity from the Moon would be too strong.
B. would still occur because each side of the Earth would feel a different gravitational force from the Moon.
C. would not occur because gravity would then be a repulsive force.
D. would not occur because the Sun would cancel out the Moon's gravity.
