$\frac{1}{2}O_2 + 2H^+ + 2e^- \rightarrow H_2O,\ E^\circ = +1.223\ V$
Will $MnO_4^-$ liberate $O_2$ from water in an acidic medium?

Options:
(1) No, because $E^\circ_{cell} = -0.287\ V$
(2) Yes, because $E^\circ_{cell} = +2.733\ V$
(3) No, because $E^\circ_{cell} = -2.733\ V$
(4) Yes, because $E^\circ_{cell} = +0.287\ V$

Correct Answer: (4)

Explanation:
$E^\circ_{cell} = 1.510 - 1.223 = +0.287\ V$.
Positive value ⇒ spontaneous reaction.
Hence, $O_2$ is liberated.

High-Weightage Physics Topics & Important NEET Questions 2026

Securing an AIR under 10,000 needs a strong and conceptual base in NEET Physics 2026. It is the most crucial section of the NEET exam, as it's even one question decides the All India Ranking. So, aspirants must minimise the negative marking and focus on the high chapter-wise weightage Physics NEET 2026 topics for smart preparation.

1. Current Electricity ( 7.95%)

Question: The current passing through the battery in the given circuit is:

(1) $2.0\ \text{A}$
(2) $0.5\ \text{A}$
(3) $2.5\ \text{A}$
(4) $1.5\ \text{A}$

Correct Answer: $1.5\ \text{A}$

Explanation:
Reduce the circuit stepwise using series and parallel combinations.
The equivalent resistance comes out to be $R_{\text{eq}} = \frac{10}{3}\Omega$.
Using Ohm’s law $I = \frac{V}{R} = \frac{5}{10/3}$.
Hence, the current through the battery is $1.5\ \text{A}$.

Question:

AB is a part of an electrical circuit. The potential difference $V_A - V_B$ at the instant when current $i = 2\ \text{A}$ and is increasing at the rate of $1\ \text{A s}^{-1}$ is:

(1) $5\ \text{V}$
(2) $6\ \text{V}$
(3) $9\ \text{V}$
(4) $10\ \text{V}$

Correct Answer: $10\ \text{V}$

Explanation:
Apply Kirchhoff’s voltage law, including inductive emf.
Inductor gives $L\frac{di}{dt} = 1 \times 1 = 1\ \text{V}$.
Resistor drop is $iR = 2 \times 2 = 4\ \text{V}$ and battery is $5\ \text{V}$.
Total potential difference becomes $1 + 5 + 4 = 10\ \text{V}$.

2. Electrostatics Potential & Capacitance (6.28%)

Question:

An electric dipole with moment $5 \times 10^{-6}\ \text{C m}$ is aligned with a uniform electric field of $4 \times 10^{5}\ \text{N C}^{-1}$. It is then rotated by $60^\circ$. The change in potential energy is:

(1) $0.8\ \text{J}$
(2) $1.0\ \text{J}$
(3) $1.2\ \text{J}$
(4) $1.5\ \text{J}$

Correct Answer: $1.0\ \text{J}$

Explanation:
Initial angle is $0^\circ$ and final angle is $60^\circ$.
Change in potential energy is $\Delta U = pE (\cos 0^\circ - \cos 60^\circ)$.
Substituting values gives $= 5 \times 10^{-6} \times 4 \times 10^{5} \times (1 - 0.5)$.
This evaluates to $2 \times 0.5 = 1.0\ \text{J}$.

3. Ray Optics & Optical Instruments (5.86%)

Question:

A microscope has objective focal length $2\ \text{cm}$ eyepiece focal length $4\ \text{cm}$ and tube length $40\ \text{cm}$. Distance of distinct vision is $25\ \text{cm}$. The magnification is:

(1) $100$
(2) $125$
(3) $150$
(4) $250$

Correct Answer: $125$

Explanation:
Magnification of a compound microscope is $M = \frac{L}{f_o} \times \left(1 + \frac{D}{f_e}\right)$.
Substituting values $= \frac{40}{2} \times \left(1 + \frac{25}{4}\right)$.
This gives $20 \times (1 + 6.25) = 20 \times 7.25$.
Hence total magnification is $125$.

4. Semiconductor Electronics (5.86%)

Question:

The output $Y$ of the given logic implementation is similar to the output of which gate:

(1) AND
(2) NAND
(3) OR
(4) NOR

Correct Answer: NOR

Explanation:
Using NAND gates we can construct other logic gates.
A NAND with same inputs behaves like a NOT gate.
The given combination first forms OR operation then inverts it.
Hence the final output is equivalent to a NOR gate.

5. Gravitation (5.86%)

Question:

The radius of Martian orbit is about 4 times that of Mercury. The Martian year is 687 Earth days. The length of one year on Mercury is:

(1) $88\ \text{days}$
(2) $225\ \text{days}$
(3) $172\ \text{days}$
(4) $124\ \text{days}$

Correct Answer: $88\ \text{days}$

Explanation:
Using Kepler’s third law $T^2 \propto R^3$.
So $\frac{T_M^2}{T_{Hg}^2} = \left(\frac{R_M}{R_{Hg}}\right)^3 = 4^3 = 64$.
Thus $\frac{T_M}{T_{Hg}} = 8$.
Hence $T_{Hg} = \frac{687}{8} \approx 86 \approx 88\ \text{days}$.
