1
Why do gases exert pressure on the walls of the container?
RRB JE
20/02/2026 / 12:45 PM - 2:15 PM
2026
✓ Answer:BGas particles move randomly and strike the walls
Gas molecules are in continuous random motion and repeatedly collide with the container walls. These collisions exert force on the walls and produce pressure.
2
Kerosene rises through the wick of a lantern because of:
RRB NTPC (Stage-I)
11/01/2021 / Shift I
2021
✓ Answer:BCapillarity
Capillary action draws kerosene through the narrow spaces in the wick.
3
Which term defines the ability of metals to be drawn into thin wires?
RRB Technicians Grade-III
23/12/2024 / Shift II
2024
✓ Answer:ADuctility
Ductility is the ability of a material to be drawn into thin wires under tension.
4
Hooke's law establishes a relation between which two physical quantities in elastic materials?
RRB RPF Constable
05/03/2025 / Shift II
2025
✓ Answer:CStress and strain
Within the proportional limit, stress is directly proportional to strain.
5
The type of stress that acts coplanar along a given cross-section of a material is called:
RRB RPF SI
12/12/2024 / Shift III
2024
✓ Answer:DShear stress
Shear stress acts tangentially, parallel to the cross-sectional surface.
6
Poisson's equation, often used to describe the elastic properties of a material, is represented by which Greek letter?
RRB NTPC (Graduate level) (Stage-II); RRB RPF SI
13/10/2025 / Shift I; 13/12/2024 / Shift I
2025; 2024
✓ Answer:CNeeta (η)
Source key: C. The source appears to mean Poisson's ratio, not Poisson's equation. Poisson's ratio is commonly denoted by ν (nu), though notation varies. The printed option names and symbols are retained; ξ is xi and η is eta.
7
Which of the following describes strain?
RRB RPF SI
03/12/2024 / Shift III
2024
✓ Answer:CDimensionless
Strain is a ratio of a change in dimension to the original dimension, so it is dimensionless.
8
When a spring's displacement becomes half its original value and its spring constant is unchanged, what happens to its potential energy?
RRB Technicians Grade-I
19/12/2024 / Shift I
2024
✓ Answer:AIt becomes one-quarter of its original value
Elastic potential energy U = kx²/2. Halving x reduces U to one-quarter.
9
When a coil spring is compressed and work is done on it, its elastic potential energy is:
RRB Group-D
04/12/2018 / Shift II
2018
✓ Answer:CIncreasing
Work done in compressing an ideal spring is stored as elastic potential energy, U = kx²/2.
10
The ability of a material to deform without breaking is called:
RRB JE
14/12/2014 / Set-2, Red Paper
2014
✓ Answer:CPlasticity
The intended answer is plasticity: the ability to undergo permanent deformation without fracture. Elasticity instead involves recovering the original shape.
