71
An object of mass m is lifted to height h above the ground. The minimum force needed to lift it is equal to its ______.
RRB Group D
15/10/2018 / Shift-III
2018
✓ Answer:BWeight
To lift at constant velocity, the upward force balances the weight mg.
72
The forces between two interacting objects are equal and opposite. Which law states this?
RRB ALP & Technician
31/08/2018 / Shift-I
2018
✓ Answer:AThird law of motion
Newton's third law states that every action has an equal and opposite reaction.
73
When a car turns on a curved road, passengers feel an outward effect opposite to the centre of the turn. This is due to ______.
RRB Group D
16/11/2018 / Shift-I
2018
✓ Answer:BInertia
Passengers tend to continue in a straight line because of inertia while the car turns.
74
What force acts on an object of mass m moving with acceleration a?
RRB Group D
12/10/2018 / Shift-II
2018
✓ Answer:Cma
Newton's second law gives F = ma.
75
A man stands in a boat in still water. If he walks towards the shore, the boat will ______.
RRB JE
14/12/2014
2014
✓ Answer:AMove away from the shore
The man pushes the boat in the opposite direction as he walks towards the shore, so the boat moves away. A shift is not provided or is cropped in the supplied scan; the available date is retained.
76
When a card placed on a glass tumbler is flicked away, a coin on it falls into the glass. Which law explains this?
RRB Group D
17/09/2018 / Shift-II
2018
✓ Answer:BLaw of inertia
The coin tends to remain at rest as the card moves away. It then falls under gravity.
77
When a force acts in the opposite direction, what is the angle between the two directions?
RRB Group D
20/09/2018 / Shift-III
2018
✓ Answer:C180°
Opposite directions make an angle of 180°.
78
When a bullet is fired from a gun, the gun recoils in the opposite direction. This is an example of Newton's ______.
RRB ALP & Technician
13/08/2018 / Shift-II
2018
✓ Answer:BThird law of motion
The gun and bullet exert equal and opposite forces on each other.
79
Which of the following has the greatest inertia?
RRB Group D
16/10/2018 / Shift-I
2018
✓ Answer:DTrains and aeroplanes
Inertia increases with mass. Trains and aeroplanes have the greatest masses among these groups.
80
Which physical quantity changes or tends to change an object's state of rest or uniform motion?
RRB ALP & Technician
21/08/2018 / Shift-II
2018
✓ Answer:CForce
Force is a push or pull that can change an object's motion.
