Question 2: Palette 2/5

AIIMS 2019 MCQ

Assertion : Paramagnetic substances get poorly attracted in magnetic field.

Reason : Because magnetic dipoles are aligned along external magnetic field weakly.

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true, but reason is not the correct explanation of assertion.

If assertion is true, but reason is false.

If both assertion and reason are false.

Question 3: Palette 3/5

AIIMS 2018 MCQ

The horizontal component of the earth's magnetic field at any place is $0.36 \times 10^{-4} \mathrm{~Wb} / \mathrm{m}^2$. If the angle of dip at that place is $60^{\circ}$, then the value of vertical component of the earth's magnetic field will be (in $\mathrm{Wb} / \mathrm{m}^2$ )

$0.12 \times 10^{-4}$

$0.24 \times 10^{-4}$

$0.40 \times 10^{-4}$

$0.622 \times 10^{-4}$

Question 4: Palette 4/5

AIIMS 2017 MCQ

The angle of dip, if dip needle oscillating in vertical plane makes 40 oscillations per min in a magnetic meridian and 30 oscillations per minute in vertical plane at right angle to the magnetic meridian is

$\theta=\sin ^{-1}(0.5625)$

$\theta=\sin ^{-1}(0.325)$

$\theta=\sin ^{-1}(0.425)$

$\theta=\sin ^{-1}(0.235)$

Question 5: Palette 5/5

AIIMS 2017 MCQ

Assertion : The magnetism of magnet is due to the spin motion of electrons.

Reason : Dipole moment of electron is smaller than that due to orbit motion around nucleus.

Both assertion and reason are true and reason is the correct explanation of assertion

Both assertion and reason are true but reason is not the correct explanation of assertion

Assertion is true but reason is false

Both assertion and reason are false.
