101
A 2 kg object accelerates at 4 m/s². What net force acts on it?
RRB Group D
22/09/2018 / Shift-II
2018
✓ Answer:D8.0 N
F = ma = 2 × 4 = 8 N.
102
All forces have ______.
RRB Group D
27/11/2018 / Shift-I
2018
✓ Answer:ABoth magnitude and direction
Force is a vector quantity, so it has both magnitude and direction.
103
The speed of a 100 kg body increases uniformly from 5 m/s to 15 m/s in 5 s. Find the force.
RRB Group D
01/10/2018 / Shift-II
2018
✓ Answer:D200 N
F = 100(15 − 5)/5 = 200 N.
104
A 1000 kg car travelling at 72 km/h stops in 4 s after braking. Find the magnitude of the braking force.
RRB Group D
27/11/2018 / Shift-I
2018
✓ Answer:D5.0 × 10³ N
72 km/h = 20 m/s. The deceleration magnitude is 20/4 = 5 m/s², so F = 1000 × 5 = 5000 N.
105
A 20 kg object accelerates at 4 m/s². Find the applied force.
RRB Group D
26/10/2018 / Shift-II
2018
✓ Answer:A80 N
F = ma = 20 × 4 = 80 N.
106
A force of 20 N gives an object an acceleration of 2 m/s². Find its mass.
RRB Group D
28/11/2018 / Shift-I
2018
✓ Answer:D10 kg
m = F/a = 20/2 = 10 kg.
107
Calculate the acceleration when a force of 100 N acts on a 50 kg object.
RRB Group D
10/12/2018 / Shift-I
2018
✓ Answer:A2 m/s²
a = F/m = 100/50 = 2 m/s².
108
Two equal forces act on a body in opposite directions. What is their resultant?
RRB Group D; RRB Group D
16/10/2018 / Shift-III; 28/09/2018 / Shift-II
2018
✓ Answer:DZero
Equal opposite forces cancel, giving zero resultant force.
109
A constant force acts on a 5 kg object for 2 s, increasing its velocity from 6 m/s to 8 m/s. Find the force.
RRB Group D
28/09/2018 / Shift-I
2018
✓ Answer:A5 N
F = 5(8 − 6)/2 = 5 N.
110
An object moves at constant speed when no ______ acts on it.
RRB Group D
04/10/2018 / Shift-I
2018
✓ Answer:CForce
The intended condition is zero net external force, under which velocity remains constant.
