NEET 2022 · Physicsde BrogliePrevious Year Question
The graph which shows the variation of the de Broglie wavelength (λ) of a particle and its associated momentum (p) is:
Answer: (D) (see figure). Answer: (d) Solution: de Broglie relation: λ = h/p, i.e.
- A.(see figure)
- B.(see figure)
- C.(see figure)
- D.(see figure)✓
Correct Answer
(D) (see figure)
Solution & Explanation
Answer: (d) Solution: de Broglie relation: λ = h/p, i.e. λ ∝ 1/p. The λ-vs-p graph is a rectangular hyperbola (λ decreases as p increases, never touching the axes).

PhysThe de Broglie wavelength of an electron in the n = 2 state of the hydrogen atom is close to (Given Bohr radius a₀ = 0.052 nm):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)PhysA bob of mass m is suspended by a light string of length l and given a horizontal velocity v₀ at the lowest point. The string goes slack at a point P where it makes an angle θ above the horizontal. The ratio of the speed v at P to the initial speed v₀ is:
