In the arrangements shown in the figures I and II, pin X and pin Y are fixed to a metal loop and a thin iron rod with the help of wax. The pins will fall at different times in arrangement

A

I

B

II

C

In both I and II

D

cannot say anything

Text Solution

Verified by Experts

The correct Answer is:
B
In set up I rate of heat transfer is same for both the pins, while in set up Il pin Y will receive more heat than X. Therefore pins fall at different times in II.
