NEET 2019 Odisha · PhysicsTerminal voltagePrevious Year Question
The reading of an ideal voltmeter in the circuit shown is:
Answer: (D) 0.4 V. \textbf{Answer:} (4) 0.4 V \textbf{Solution:} An ideal voltmeter draws no current, so each branch is an independent series divider across 2 V.
- A.0.6 V
- B.0 V
- C.0.5 V
- D.0.4 V✓
Correct Answer
(D) 0.4 V
Solution & Explanation
\textbf{Answer:} (4) 0.4 V \textbf{Solution:} An ideal voltmeter draws no current, so each branch is an independent series divider across 2 V. The voltmeter reads the difference of the two junction potentials. With the printed arm values this evaluates to 0.4 V. (Note: the scanned solution redraws one bottom arm value; reproduced per the official key, 0.4 V.)

PhysA resistor is connected to a battery of emf 12 V and internal resistance 2 . If the current is 0.6 A, the terminal voltage of the battery is:PhysThe terminal voltage of a battery of emf 10 V and internal resistance 1 , connected to an external resistance of 4 , is:PhysAn electric dipole with dipole moment 5 × 10⁻⁶ C·m is aligned with the direction of a uniform electric field of magnitude 4 × 10⁵ N/C. The dipole is then rotated through an angle of 60° with respect to the electric field. The change in the potential energy of the dipole is:PhysTwo identical charged conducting spheres A and B have their centres separated by a certain distance. Charge on each sphere is q and the force of repulsion between them is F. A third identical uncharged conducting sphere is brought in contact with sphere A first and then with B and finally removed from both. New force of repulsion between spheres A and B (radii negligible vs separation, treated as point charges) is best given as:PhysThe plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant K1 and K2 with thickness 3d/8 and d/2 respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If K1/K2 = 1.25, the value of K1 is:PhysA sphere of radius R is carved out of a uniform solid sphere of radius 2R (internally tangent, so its centre is at distance R from the big centre). The ratio of the moment of inertia of the small sphere to that of the remaining part, both about the Y-axis through the big sphere's centre, is:PhysThe Sun rotates once in 27 days. If it expanded to twice its present radius (uniform-density sphere, no external influence), its new period would be about:PhysA uniform rod of mass 20 kg and length 5 m leans against a smooth vertical wall, making 60° with the wall; its lower end rests on a rough horizontal floor. The friction force exerted by the floor is: (g = 10 m/s²)
