1
Which of the following options represents the equation of work done?
RRB ALP (Stage-II); RRB ALP (Stage-II); RRB Technician Grade-III; RRB Group D
02/05/2025 / Shift-II; 02/05/2025 / Shift-I; 28/12/2024 / Shift-II; 08/10/2018 / Shift-I
2025; 2024; 2018
✓ Answer:BWork done = Force × Displacement
Work equals force multiplied by displacement in the direction of the force: W = F × s.
2
If a ball is thrown upwards, the work done by gravity on the ball will be:
RRB ALP (Stage-II)
02/05/2025 / Shift-II
2025
✓ Answer:CNegative
Gravity acts downward while the displacement is upward, so the work done by gravity is negative.
3
A force of 6 N displaces a body 2 metres in the direction of the force. Find the work done.
RRB ALP (Stage-II); RRB ALP (Stage-II)
02/05/2025 / Shift-II; 06/05/2025 / Shift-II
2025
✓ Answer:A12 J
W = F × s = 6 × 2 = 12 J.
4
A porter lifts a 10 kg object from the ground and places it 2.5 metres above the ground on his head. Calculate the work done on the object.
RRB ALP (Stage-II)
06/05/2025 / Shift-II
2025
✓ Answer:A250 J
Using g = 10 m/s², W = mgh = 10 × 10 × 2.5 = 250 J.
5
Which statement is correct regarding negative work?
RRB ALP (Stage-II); RRB Technician Grade-III; RRB Group D
02/05/2025 / Shift-I; 26/12/2024 / Shift-II; 03/12/2018 / Shift-III
2025; 2024; 2018
✓ Answer:AWhen force acts opposite to displacement, work done is negative.
W = Fs cos θ. Opposite force and displacement give θ = 180° and negative work.
6
An object of mass 50 kg moves along a horizontal line. What is the work done by gravity? (g = 10 m/s²)
RRB ALP (Stage-II)
02/05/2025 / Shift-I
2025
✓ Answer:B0
Gravity is perpendicular to the horizontal displacement, so W = Fs cos 90° = 0.
