They are going to repel each other , as both the south poles of the magnets are facing each other .

Two same poles repel whereas two different poles attract each other. There are two poles of a magnet, to be precise anyway, namely the North and South Pole

InThe first and second magnets, the south poles are facing each other , so they are going to repel.

Ans 14:

Class : Class 3
they need to repel cause same poles repel

Ans 15:

Class : Class 5
I thought that the whole magnet was north and south each

why answer is A?????????????????????????????????????

Where is the figure?

Ans 4:

Class : Class 6
My tab is being discriminated! I didn't get the figure.

Ans 5:

Class : Class 8

Ans 6:

Class : Class 10
so ans should be option B

Ans 7:

Class : Class 6
THERE IS NO FIGURE GIVEN. NOT GOOD!!!

Ans 8:

Class : Class 6
The qs is wrong as it should be "similar batteries" as for the glow of the bulb one battery one work at all .

When a battery is connected in the same order, it will cause a short circuit. On the other hand, Connecting it in the reverse order will brighten it up. The answer is b.

Ans 12:

Class : Class 8
It is A

Ans 13:

Class : Class 10
no figure !!!!!!!!!!!!!!!!!!!!!!!!!!!

Ans 14:

Class : Class 10
where is the figure

Ans 17:

Class : Class 7
why is figure not given?

Ans 18:

Class : Class 9
THERE IS NO FIGURE

Ans 19:

Class : Class 9
WHY THIS ANSWER??????

Ans 20:

Class : Class 10
For all those who say that the figure is not there, the question refers to the figure in the previous question, that is, Q.9.A is the correct option because by in the same order it means the same order in which the cells of the battery are connected, that is, positive terminal should be connected to the negative terminal, through the wires.I, therefore, believe that option A is the correct option.If you did not understand the above explanation, then imagine that the two probes are just at the side of the battery. Now imagine that another battery is between the two probes in the same order like the other battery. Now can you imagine the circuit complete and understand why option A is correct?Hope that this comment is helpful.

Class : Class 8
very nice photo

Ans 22:

Class : Class 8
I think it is the photo in the previous question

Ans 23:

Class : Class 9
For the people who didn't see the figure, the figure is the same as the one in the previous question. However, even I don't understand how the answer is (a). It should be (b)

Ans 24:

Class : Class 10
There is no figure!!!!!

Ans 25:

Class : Class 10
the figure is the same as in question 9........but the ans is not option A because if we add a battery between the probes in the same order , then as overall , the negative terminal of the two batteries will come in contact and as we know both the batteries will push electricity against each other and we have to subtract its voltage , thus resulting in decrease in the amount of electricity or short circuit may happen.

Ans 26:

Class : Class 6
the question is from the figure in question 9
