In the two 'set-ups' X and Y, shown, the wires AB and PQR
are made of the same material and have equal thickness. The length of the wire AB, (in the set-up X) is equal to the diameter (= PR) of the semi-circle,
formed by the wire PQR, (in the set-up 'Y'). Pins, P1 and P2, are attached, to
wires AB and PQR respectively
, with the help of wax. Which of the two pins, P1 or P2, will fall off later? Give reason for your answer.
