RRB Group D
20/09/2018 / Shift-III
2018
✓ Answer:A20 J
W = Fs = 10 × 2 = 20 J.
353
In which situation is no work done?
RRB Group D
19/09/2018 / Shift-III
2018
✓ Answer:AKapil stands with a 10 kg load on his shoulder.
The stationary load has zero displacement, so the work done on it is zero.
354
A porter raises 12 kg of goods from the ground onto his head 1.5 m above the ground. Find the work done. (g = 10 m/s²)
RRB Group D
04/10/2018 / Shift-II
2018
✓ Answer:C180 J
W = mgh = 12 × 10 × 1.5 = 180 J.
355
An object moves 10 m in the direction of a 10 N force. Find the work done.
RRB Group D
31/10/2018 / Shift-II
2018
✓ Answer:C100 J
W = Fs = 10 × 10 = 100 J.
356
Work done by a force is positive when:
RRB Group D
19/09/2018 / Shift-III
2018
✓ Answer:ADisplacement is in the force direction.
W = Fs cos 0° = Fs > 0 for displacement along the force.
357
A force of 25 N moves an object 5 m in the force direction. Find the work done.
RRB Group D
26/10/2018 / Shift-II
2018
✓ Answer:C125 J
W = Fs = 25 × 5 = 125 J.
358
A force of 50 N displaces an object 10 m in its direction. Find the work done.
RRB Group D
03/12/2018 / Shift-III
2018
✓ Answer:A500 J
W = Fs = 50 × 10 = 500 J.
359
A 5.0 kg object is raised 2 m. Find the work done. (g = 9.8 m/s²)
RRB ALP & Technician
20/08/2018 / Shift-III
2018
✓ Answer:D98 J
W = mgh = 5 × 9.8 × 2 = 98 J.
360
The rate of doing work is called:
RRB ALP (Stage-II); RRB Technician Grade-III; RRB ALP & Technician; RRB Group D; RRB Group D; RRB Group D; RRB Group D; RRB Group D
02/05/2025 / Shift-II; 26/12/2024 / Shift-III; 14/08/2018 / Shift-II; 17/09/2018 / Shift-III; 19/09/2018 / Shift-I; 15/10/2018 / Shift-II; 05/10/2018 / Shift-I; 22/10/2018 / Shift-III
2025; 2024; 2018
✓ Answer:CPower
P = W/t defines power.
