Re: IIT JEE Question Paper

You want IIT JEE Old question paper so I have it in pdf file which I am sharing with you. Following are some questions given in pdf file:

1. In the determination of Young’s modulus 2
4MLg
Y
d
= p l
by using Searle’s method, a wire of length L = 2m
and diameter d = 0.5 mm is used. For a load M = 2.5 kg, an extension l = 0.25 mm in the length of the wire
is observed. Quantities d and l are measured using a screw gauge and a micrometer, respectively. They
have the same pitch of 0.5 mm. The number of divisions on their circular scale is 100. The contributions to
the maximum probable error of the Y measurement
(A) due to the errors in the measurements of d and l are the same.
(B) due to the error in the measurement of d is twice that due to the error in the measurement of l.
(C) due to the error in the measurement of l is twice that due to the error in the measurement of d.
(D) due to the error in the measurement of d is four times that due to the error in the measurement of l.

2. A small mass m is attached to a massless string whose other end is fixed at P as shown in the figure. The
mass is undergoing circular motion in the x-y plane with centre at O and constant angular speed w. If the
angular momentum of the system, calculated about O and P are denoted by O L
r
and P L
r
respectively, then
z
P
O m
w
(A) O L
r
and P L
r
do not vary with time.
(B) O L
r
varies with time while P L
r
remains constant.
(C) O L
r
remains constant while P L
r
varies with time.
(D) O L
r
and P L
r
both vary with time.

For complete questions you can free download attached pdf file which is free for you.

Re: IIT JEE Question Paper

As you want to get IIT JEE question paper so here I am giving you some questions of that paper:

On heating an aliphatic primary amine with chloroform and ethanolic potassium hydroxide, the
organic compound formed is :
(1) an alkyl cyanide (2) an alkyl isocyanide
(3) an alkanol (4) an alkanediol

For the estimation of nitrogen, 1.4 g of an organic compound was digested by Kjeldahl method
and the evolved ammonia was absorbed in 60 mL of M
10
sulphuric acid. The unreacted acid
required 20 mL of M
10
sodium hydroxide for complete neutralization. The percentage of nitrogen
in the compound is :
(1) 3 % (2) 5 % (3) 6 % (4) 10 %

Consider separate solutions of 0.500 M C2H5OH(aq), 0.100 M Mg3(PO4)2(aq), 0.250 M KBr(aq)
and 0.125 M Na3PO4(aq) at 25°C. Which statement is true about these solutions, assuming all
salts to be strong electrolytes ?
(1) 0.125 M Na3PO4(aq) has the highest osmotic pressure.
(2) 0.500 M C2H5OH(aq) has the highest osmotic pressure.
(3) They all have the same osmotic pressure.
(4) 0.100 M Mg3(PO4)2(aq) has the highest osmotic pressure.
(3)
All solutions have same osmotic pressure.

Resistance of 0.2 M solution of an electrolyte is 50 Ω. The specific conductance of the solution is
1.4 S m−1. The resistance of 0.5 M solution of the same electrolyte is 280 Ω. The molar
conductivity of 0.5 M solution of the electrolyte in S m2 mol−1 is :
(1) 5 × 103 (2) 5 × 102 (3) 5 × 10−4 (4) 5 × 10−3

Which one of the following properties is not shown by NO ?
(1) It combines with oxygen to form nitrogen dioxide
(2) It′s bond order is 2.5
(3) It is diamagnetic in gaseous state
(4) It is a neutral oxide
