    Few Solved Questions from JEE Main 2021 Paper

    1. (Subject - Physics, Chapter - Current Electricity, Shift - 20 July shift 1)

    Question:-

    1719990199500

    The value of current in the 6\; \Omega resistance is :

    1. 4A

    2. 8A

    3. 10A

    4. 6A

    UPES B.Tech Admissions 2026

    Last Date to Apply: 26th March | Ranked #43 among Engineering colleges in India by NIRF | Highest Package 1.3 CR , 100% Placements

    Answer- 3) 10A

    Solution:-

    1719990199548

    Applying KCL at the junction with voltage x (assigned)

    1719990199447

    By KCL,

    \text{I}_{1}+\text{I}_{2}+\text{I}_{3}= 0

    \left(\frac{x-90}{5}\right)+\left(\frac{x-140}{20}\right)+\left(\frac{x-0}{6}\right)=0

    \begin{aligned} 24 x-24 \times 90+6 x-6 \times 140+20 x=0 \\ \end{aligned}

    \begin{aligned} 50 x &=24 \times 90+6 \times 140 \\ \end{aligned}

    \begin{aligned} &=6[4 \times 90+140] \\ \end{aligned}

    \begin{aligned} 50 x &=3000 \\ \end{aligned}

    \begin{aligned} x &=60 \mathrm{~V} \end{aligned}

    Current through 6\; \Omega resistor is

    I_{3}=\left(\frac{x-0}{6}\right)=\left(\frac{60-0}{6}\right)=10 \mathrm{~A}

    The correct option is (3)

    2. (Subject - Maths, Chapter - Integral Calculus, Shift - 27 August Shift 1)

    Question:- \int_{6}^{16} \frac{\log _{\mathrm{e}} x^{2}}{\log _{\mathrm{e}} x^{2}+\log _{\mathrm{e}}\left(x^{2}-44 x+484\right)} \mathrm{d} x is equal to:

    1. 5

    2. 10

    3. 8

    4. 6

    Answer- 1) 5

    Solution:-

    Let\, I= \int_{6}^{16}\frac{\log_{e} x^{2} }{\log_{e}x^{2}+\log_{e}\left ( 22-x \right )^{2}}dx ---\left ( 1 \right )

    Using properties of Integral

    I= \int_{6}^{16}\frac{\log_{e} \left ( 6+16-x \right )^{2}}{\log_{e}\left ( 6+16-x \right )^{2}+\log_{e}\left ( 22-\left ( 6+16-x \right ) \right )^{2}}dx

    \Rightarrow I= \int_{6}^{16}\frac{\log_{e} \left ( 22-x \right )^{2}}{\log_{e}\left ( 22-x \right )^{2}+\log_{e}x^{2}}dx---\left ( 2 \right )

    Adding (1) and (2)

    2I= \int_{6}^{16}\frac{\log_{e}x^{2}+\log_{e}\left ( 22-x \right )^{2}}{\log_{e}x^{2}+\log_{e}\left ( 22-x \right )^{2}}dx

    \Rightarrow 2I= \int_{6}^{16}dx= 10

    \Rightarrow I= 5

    Hence, the answer is the option 1.

    3. (Subject - Chemistry, Chapter - Equilibrium, Shift - 31 August Shift 1)

    Question:-

    \mathrm{A}_{3} \mathrm{~B}_{2} is a sparingly soluble salt of molar mass \mathrm{M (g\ mol^{-1})} and solubility x \mathrm{~g} \mathrm{}^{-1}. The solubility product satisfies \mathrm{K}_{\mathrm{sp}}=a\left(\frac{x}{\mathrm{M}}\right)^{5}. The value of a is __________. (Integer answer)

    Answer- (108)

    Solution:-

    Given,

    \mathrm{solubility\, of\, A_{3}B_{2}}= x\ \mathrm{gL^{-1}}

    \mathrm{\therefore solubility\, in\,\frac{moles}{lit}= \left ( \frac{x}{M} \right )\, mol\, L^{-1}}

    {\therefore \mathrm{s}= \left ( \frac{x}{\mathrm{M}} \right )}

    Now, \mathrm{ A_{3}B_{2}} dissolves as

    \mathrm{A_{3}B_{2}\rightleftharpoons 3A^{2+}+2B^{3-}}

    \quad - \quad\quad\quad 3s\quad\quad\quad2s

    Expression for solubility product gives us

    \mathrm{\therefore K_{sp}= \left ( 3s \right )^{3}\left ( 2s \right )^{2}} \mathrm{=108 \, s^{5}} \mathrm{=108 \left ( \frac{x}{M} \right )^{5}}

    Hence, the answer is (108).
