Default Re: West Bengal Joint Entrance Examination Question Paper Download

The previous year Chemistry Question Paper of WBJEE or West Bengal Joint Entrance Examination is as follows:

1. Two particles of mass m1 and m2 ,approach each other due to their mutual gravitational attraction only. Then
(A) accelerations of both the particles are equal
(B) acceleration of the particle of mass m1 is proportional to m1
(C) acceleration of the particle of mass m1 is proportional to m2
(D) acceleration of the particle of mass m1 is inversely proportional to m1

2. Three bodies of the same material and having masses m, m and 3m are at temperatures 400C, 500C and 600C respectively. If the bodies are brought in thermal contact, the final temperature will be
(A) 450C
(B) 540C
(C) 520C
(D) 480C

3. A simple pendulum of length L swings in a vertical plane. The tension of the string when it makes an angle  with the vertical and the bob of mass m moves with a speed v is (g is the gravitational acceleration
(A) mv2/L

(B) mg cos + mv2/L
(C) mg cos – mv2
/L (D) mg cos

4. A metal wire of circular cross-section has a resistance R1. The wire is now stretched without breaking so that its length is doubled and the density is assumed to remain the same. If the resistance of the wire now becomes R2 then R2 : R1 is

(A) 1 : 1
(B) 1 : 2
(C) 4 : 1
(D) 1 : 4
