And yeah, you can also download a PDF of these questions. Just read it down.

## Physics General Knowledge MCQ

⇒It is easier to roll a stone up a sloping road than to lift it vertical upwards because
work done in rolling a stone is less than in lifting it
work done in lifting the stone is equal to rolling it
work done in rolling is more than in lifting
work done in both is same but the rate of doing work is less in rolling

⇒Let a thin capillary tube be replaced with another tube of insufficient length then, we find water
depressed
will not rise
change its meniscus
will overflow

⇒Large transformers, when used for some time, become very hot and are cooled by circulating oil. The heating of the transformer is due to
both the heating effect of current and hysteresis loss
the heating effect of current alone
hysteresis loss alone
intense sunlight at noon

⇒Out of the following pairs, choose the pair in which the physical quantities do not have identical dimension?
Pressure and Young’s modules
Planck’s constant and Angular momentum
Impulse and moment of force
Force and rate of change of linear momentum

⇒Stars appears to move from east to west because
all stars move from east to west
the earth rotates from east to west
the earth rotates from west to east
the background of the stars moves from west to east

⇒If two bodies of different masses, initially at rest, are acted upon by the same force for the same time, then the both bodies acquire the same
velocity
acceleration
kinetic Energy
Momentum

⇒Planets do not twinkle because
they emit light of a constant intensity
their distance from the earth does not change with time
they are nearer to earth and hence we receive a greater amount of light and, therefore minor variations in the intensity are not noticeable
they are very far away from the earth resulting in decrease in intensity of light

⇒Out of the following, which is not emitted by radioactive substance?
Neutrons
Alpha particles
Electrons

⇒Find the maximum velocity for the overturn of a car moving on a circular track of radius 100 m. The co-efficient of friction between the road and tyre is 0.2
14 m/s
0.14 m/s
140 m/s
1.4 km/s

⇒Of the following properties of a wave, the one that is independent of the other is its
Wave length
amplitude
Velocity
frequency

⇒Point A is at a lower electrical potential than point B. An electron between them on the line joining them will
move towards B
move towards A
move at right angles to the line joining A and B
remain at rest

⇒Materials for rain-proof coats and tents owe their water-proof properties to
surface tension
viscosity
specific gravity
elasticity

⇒On a rainy day, small oil films on water show brilliant colors. This is due to
diffraction
interference
dispersion
polarization

⇒On a clean glass plate a drop of water spreads to form a thin layer whereas a drop of mercury remains almost spherical because
density of mercury is greater than that of water
mercury is a metal
cohesion of mercury is greater than its adhesion with glass
cohesion of water is greater than its adhesion with glass
