RRB Group D
28/09/2018 / Shift-II
2018
✓ Answer:A200 N
F = ma = 25 × 8 = 200 N.
112
A constant force acts on an 8 kg object for 3 s, increasing its velocity from 4 m/s to 6 m/s. Find the force.
RRB Group D
27/09/2018 / Shift-I
2018
✓ Answer:A5.33 N
F = 8(6 − 4)/3 = 16/3 ≈ 5.33 N.
113
An object moves at constant speed when there is no ______ acting on it.
RRB Group D
04/10/2018 / Shift-I
2018
✓ Answer:CForce
The intended meaning is no net external force. With zero net force, velocity remains constant.
114
The property of a substance that resists a change in shape despite an applied ______ is called ______.
RRB Group D
05/10/2018 / Shift-I
2018
✓ Answer:CExternal force, rigidity
Rigidity is resistance to a change in shape under an external force.
115
A 100 kg object's velocity increases uniformly from 5 m/s to 17 m/s in 6 s. Find the force.
RRB Group D
26/09/2018 / Shift-I
2018
✓ Answer:B200 N
F = 100(17 − 5)/6 = 200 N.
116
Which of the following never occurs alone in nature?
RRB ALP & Technician
09/08/2018 / Shift-II
2018
✓ Answer:BForce
Forces arise from interactions. Every action force has an equal and opposite reaction force on another body.
117
A 15 kg mass accelerates at 5 m/s². What force acts on it?
RRB Group D
26/10/2018 / Shift-III
2018
✓ Answer:D75 N
F = ma = 15 × 5 = 75 N.
118
______ never occurs alone in nature.
RRB Group D
20/09/2018 / Shift-II
2018
✓ Answer:AForce
Forces occur in action-reaction pairs, acting on different bodies.
119
An object's momentum changes by 10 kg·m/s in 0.02 s. Find the force.
RRB Group D
05/11/2018 / Shift-II
2018
✓ Answer:C500 N
F = Δp/Δt = 10/0.02 = 500 N.
120
