A thin plano-convex lens, acts like a concave mirror of focal length 0.2 m, when silvered from its plane surface. The refractive index of the material of the lens is 1.5. The radius of curvature, of the convex surface, of the lens will be

Detailed Solution for BITSAT Mock Test - 7 - Question 3

After silvering the plane surface, plano convex lens behaves as a concave mirror of focal length

But F = 0.2 m
∴ flens = 2F = 2 × 0.2 = 0.4 m
Now from lens maker's formula

= (1.5 - 1) ×
⇒ R1 = 0.5 × 0.4 = 0.2 m

A right-angled prism is to be made by selecting a proper material and angles A and B (B ≤ A), as shown in the figure. It is desired that a ray of light incident on face AB emerges parallel to the incident direction after two internal reflections. What should be the minimum refractive index (n) for this to be possible?
Detailed Solution for BITSAT Mock Test - 7 - Question 5

Referring to Fig. the path of the ray is PQRS suffering internal reflections at Q and R.
It is clear from the figure that angles α and β should be greater than the critical angle given by
sin ic =

Also angle A = α and angle B = β. Since A ≥ B; β ≤ α, the minimum value of n is given by ≤ sin β
∴ nmin =
So the correct choice is (2).

If a photon of wavelength 150 pm strikes an atom and one of its inner bound electrons is ejected with a velocity of 1.5 × 107 ms-1, then what is the energy with which it is bound to the nucleus?
Detailed Solution for BITSAT Mock Test - 7 - Question 9

Energy of the photon,
E = =
= 1.32 × 10-15 J
Energy of the ejected electron,
E' = mv2
=
= 1.024 × 10-16
Total energy of the photon = Binding energy of the electron + Energy of the ejected electron
1.32 x 10-15 = Binding energy + 1.024 x 10-16
∴ Binding energy = (1.32 x 10-15) - (1.024 x 10-16)
= 1.2176 x 10-15 J
=
= 7.6 x 103 eV

Which of the following oxides is expected to exhibit paramagnetic behaviour?
Detailed Solution for BITSAT Mock Test - 7 - Question 10

The structure of ClO2 is represented as follows:

Due to the presence of three electron bonds, ClO2 has odd number of electrons. Hence, ClO2 is paramagnetic in nature.

One mole of magnesium in the vapour state absorbs 1200 kJ mol-1 energy. If the first and second ionisation energies of Mg are 750 kJ mol-1 and 1450 kJ mol-1, respectively, then the final composition of the mixture is
Detailed Solution for BITSAT Mock Test - 7 - Question 14

One mole of Mg in the vapour state absorbs 1200 kJ/mol of energy.
Energy absorbed in the ionisation of 1 mole of Mg to Mg+(g) = 750 kJ
Energy left unused = 1200 - 750 = 450 kJ
Percentage of Mg+ (g) converted into Mg2+ (g)
=
Hence, the percentage of Mg+(g) = 100 - 31 = 69%

The distance between the pair of parallel lines represented by the expression x2 + 2xy + y2 - 8ax - 8ay - 9a2 = 0 is
Detailed Solution for BITSAT Mock Test - 7 - Question 27
The given equation can be written as (x + y)2 - 8a(x + y) - 9a2 = 0
Now, put t = x + y, the equation becomes t2 - 8at - 9a2 = 0
i.e., t2 - 9at + at - 9a2 = 0
(t - 9a)(t + a) = 0
Hence, the equations are x + y - 9a = 0 and x + y + a = 0
The given pair of straight lines are x + y - 9a = 0 and x + y + a = 0
