The first shift of Uttar Pradesh State Examination (UPSEE/UPTU) 2017 Examination was held on April 16, 2017. The question paper with its detailed solution and answer key has been released on the official website of UPSEE. According to the feedback of students, the difficulty level of this paper was moderate Students can download UPSEE/UPTU 2017 Question Paper and its detailed solution from this article. This paper will be very useful for those who are going to appear for the exam on 22 and 23 April 2017.

**Few questions from the Question Paper are given below:**

**Q.** A light beam consists of two types of photons. In one type each photon has energy 2eV and in other type each photon has energy 3eV. The light beam is incident on a photoelectric material of work function 1eV. The maximum kinetic energy of emitted photoelectron is :

(A) 1eV

(B) 2eV

(C) 3eV

(D) 4eV

**Correct Option: (B)**

**Sol.**

KE _{max} = hν_{max} - Φ = 3 - 1 = 2 eV

**Q.** Gravitational force acts on a particle due to fixed uniform solid sphere. Neglect other forces. Then particle :

(A) experiences a force directed along the radial direction only.

(B) always moves normal to the radial direction

(C) always moves in the radial direction only.

(D) always moves in circular orbit.

**Correct Option: (A)**

**Sol.**

Circular motion is a special case in gravitational field. There may be straight line,elliptical paths, but force will be always directed toward the centre of the sphere.

**Q.** Which of the following statement is correct ?

(A) BCl_{3} and AlCl_{3} are both Lewis acids and BCl_{3} is stronger than AlCl_{3}

(B) BCl_{3} and AlCl_{3} are both Lewis acids and AlCl_{3} is stronger than BCl_{3}

(C) BCl_{3} and AlCl_{3} are both equally strong Lewis acid

(D) Both BCl_{3} and AlCl_{3} are not Lewis acids.

**Correct Option: (A)**

**Sol.**

BCl_{3} and AlCl_{3} both are Lewis acids but BCl_{3} is more electron deficient than AlCl_{3 } so BCl_{3} is stronger Lewis acid than AlCl_{3} due to high electron negativity.(E.N. B-2.0,Al 1.5)

**Q.** Given y = x^{2} . As x→2, y→4 what must the value of δ be for which from | x – 2 |< δ it follows that

| y – 4 | < ∈ = 0.001 ?

(A) 0 < δ < 0.00025

(B) 0.03 < δ < 0.05

(C) 0.2 < δ < 0.25

(D) 0.4< δ < 0.5

Sol.

Using,

| x – 2 |< δ, we get | y – 4 | < δ(δ + 4), which is less than ∈

So, δ < √(∈ + 4) - 2

For , ∈ = 0.001, the δ < 0.00025
