SUMMARY
The discussion centers on the relationship between centripetal force, radius, and speed in circular motion, specifically when both the centripetal force and radius are doubled. According to the equation F = mv²/r, when substituting 2 for both F and r, the resulting speed increases by a factor of 2, confirming that the correct answer is (B). Participants expressed confusion over the wording of the question and the calculations involved, but the consensus is that the speed does not quadruple as initially suggested by some users.
