MCQ

Reeta puts two different objects in each of the following containers.

Container: Copper coin and iron nail.
Container: Steel nail and aluminium earring.
Container: Marble and gold coin.
Container: Nickel coin and steel nail.

She can use a magnet to separate the objects in containers:

✓
$(i)$ and $(ii).$
B
$(i), (ii)$ and $(iii).$
C
$(i), (ii)$ and $(iv).$
D
$(i), (ii), (iii)$ and $(iv).$

✓

Answer

Correct option: A.

$(i)$ and $(ii).$

In containers $(i)$ and $(ii),$ iron nail and steel nail are magnetic while copper coin and aluminium earring are non-magnetic. In container $(iii),$ both marble and gold coin are non-magnetic and in container $(iv),$ both nickel coin and steel nail are magnetic. So, Reeta can use a magnet to separate the objects only in containers $(i)$ and $(ii).$
