Ans 3:

Ashwak from Cambridge International School, Saudi Al Dera
Class : Class 8
Yes it should be A ......because it is not possible that some of the iron bar is magnet and some is iron ....in the given figure starting of the stroke is point is Q but before that is point P which is starting of the rod so the CORRECT answer is A ..
