As mentioned , the physics paper(code:55/3 set-3) this year , contains a inaccurate question which is not specifying clearly that what we actually need to do in it.

In section C Q19 part (a) deals with a ring of relative permeability has winding of insulated copper .In this question we are not specified about how the copper wire has been rapped on the ring.

There can be two totally different ways of doing such a thing . One way is to cover it as we do it in case of toroid . Other way out to do the same is to wind the copper wires along the axle (circumference ) of the the ring.

It is not at all clear about the style of rapping the copper windings . Which case in need to be taken into account is not at all specified in the question paper .

We request the CBSE Examination Board to make the correction liberal so that it won't affect our grades.
