Question

Choose the correct option.

A metal bar PQ is suspended freely . It always comes to rest with its end Q pointing towards north. Another bar XY of same material settles in no definite direction when freely suspended. The two bars are brought closed together.

Which of the following is true?
a) end Q attracts X but repels Y
b) end Q attracts Y but repels X
c) end Q attracts both ends X and Y
d) end Q repels both ends X and Y​

Answer 1

C) end Q attracts both X and Y

Reason: The metal bar PQ is magnetized and has magnetic properties in it, that's I why the point Q is pointing towards the north. The XY bar doesnt point towards any specific direction because it isn't magnetized and doesn't have magnetic properties in it, and that's why it gets attracted by Q and it's both ends.
