QUESTION
1 The mass number and the atomic number of A6 are given by:
2The maximum vertical height to which a man can throw a ball is 136m. The maximum horizontal
distance upto which he can throw the same ball is
3Given below are two statements :
Statement I : An elevator can go up or down with uniform speed when its weight is balanced with
the tension of its cable.
Statement II : Force exerted by the floor of an elevator on the foot of a person standing on it is
more than his/her weight when the elevator goes down with increasing speed.
In the light of the above statements, choose the correct answer from the options given below
4The weight of a body at the surface of earth is 18N. The weight of the body at an altitude of
3200km above the earth’s surface is (given, radius of earth Re = 6400 km):
5Two long straight wires P and Q carrying equal current 10A each were kept parallel to each other
at 5cm distance. Magnitude of magnetic force experienced by 10cm length of wire P is F1.If
distance between wires is halved and currents on them are doubled, force F2 on 10cm length of
wire P will be :
7If two charges q1 and q2 are separated with distance ‘d’ and placed in a medium of dielectric
constant K. What will be the equivalent distance between charges in air for the same electrostatic
force ?
8From the photoelectric effect experiment, following observations are made.
Identify which of these are correct.
(A) The stopping potential depends only on the work function of the metal.
(B) The saturation current increases as the intensity of incident light increases.
(C) The maximum kinetic energy of a photo electron depends on the intensity of
the incident light.
(D) Photoelectric effect can be explained using wave theory of light.
9 Given below are two statements :
Statement I : The temperature of a gas is 73 C.
When the gas is heated to 527 C,
the root mean
square speed of the molecules is doubled.
Statement II : The product of pressure and volume of an ideal gas will be equal to translational
kinetic energy of the molecules.
10In E
andK
represent electric field and propagation vectors of the EM waves in vacuum, then
magnetic field vector is given by :
11 Given below are two statements : one is labelled as Assertion A and the other is labelled as
Reason R
Assertion A : Photodiodes are preferably operated in reverse bias condition for light intensity
measurement.
Reason R : The current in the forwards bias is more than the current in the reverse bias for a p –
n junction diode.
In the light of the above statements, choose the correct answer from the options given below :
12 Assume that protons and neutrons have equal masses. Mass of a nucleon is 1.6 × 10^-27 kg and
radius of nucleus is 1.5 × 10^-15 A^1/3 m. The approximate ratio of the nuclear density and water
density is n × 1013. The value of n is_.
13A block of a mass 2kg is attached with two
identical springs of spring constant 20N/m each.
The block is placed on a frictionless surface and
2Kg
the ends of the springs are attached to rigid supports (see figure). When the mass is displaced
from its equilibrium position, it executes a simple harmonic motion. The time period of oscillation
is
x
in SI unit.
The value of x is __________.
