An object floats on a liquid's surface when its average density is:
RRB Technicians Grade-III
26/12/2024 / Shift I
2024
✓ Answer:CLess than the liquid's density
An object less dense than the liquid can float partly submerged. Equal densities give neutral buoyancy when submerged.
32
What happens to the water level in a glass when a floating ice cube completely melts?
RRB Group-D
01/10/2018 / Shift II
2018
✓ Answer:CThe water level remains the same
Floating ice displaces water equal to its weight. Its meltwater occupies the same volume as the water previously displaced.
Pressure is normal force divided by area, P = F/A.
34
A solid iron rod is placed on water. If the upward force from water exceeds its weight, what happens according to the stated condition?
RRB Technicians Grade-III
20/12/2024 / Shift II
2024
✓ Answer:DIt floats on the surface
Source key: D. A net upward force makes an object rise until buoyancy balances its weight. However, an ordinary solid iron rod is denser than water and normally sinks; the question's hypothetical condition is inconsistent with that example.
35
When an object sinks under its weight, the fluid's upthrust is:
RRB Group-D
09/10/2018 / Shift II
2018
✓ Answer:BLess than its weight
The buoyant force is smaller than the object's weight; drag may also act during descent.
36
Pressure is determined from:
RRB NTPC (Stage-I)
30/03/2016 / Shift I
2016
✓ Answer:CForce and area
Pressure equals normal force divided by the area over which it acts.
37
Which statements are correct? A. Weight acts vertically downward on an object. B. Buoyant force acts on an object perpendicular to its surface.
RRB Technicians Grade-III
20/12/2024 / Shift II
2024
✓ Answer:DBoth A and B are true
Source key: D. A is correct, but B confuses local pressure forces with their resultant. Fluid pressure acts normally on each surface element; the resultant buoyant force acts upward. Strictly, B is the scientifically correct option for the printed wording.
38
Upthrust and an object's weight act:
RRB Group-D
05/10/2018 / Shift III
2018
✓ Answer:BIn opposite directions
Buoyancy acts upward while weight acts downward.
39
For a fixed force, pressure on a smaller area is:
RRB Group-D
10/10/2018 / Shift I
2018
✓ Answer:CGreater
Since P = F/A, reducing area while keeping force fixed increases pressure.
40
An empty airtight bottle is pushed underwater and rises when released. Why?
RRB Minis. & Iso. Category (Librarian); RRB ALP (Stage-I)
12/09/2025 / Shift I; 26/11/2024 / Shift I
2025; 2024
✓ Answer:CThe buoyant force exceeds its weight
When the submerged bottle displaces water weighing more than the bottle, the net force is upward.
