Re: WBJEE Engineering Question paper in Bengali

You are looking for WBJEE Engineering Question paper, here I am providing:

Two soap bubbles of radii r and 2r are connected by a capillary tube-valve arrangement as shown in the diagram. The
valve is now opened. Then which one of the following will result:
(A) the radii of the bubbles will remain unchanged
(B) the bubbles will have equal radii
(C) The radius of the smaller bubble will increase and that of the bigger bubble will decrease
(D) The radius of the smaller bubble will decrease and that of the bigger bubble will increase
Ans : (D)

An ideal mono-atomic gas of given mass is heated at constant pressure. In this process, the fraction of supplied heat
energy used for the increase of the internal energy of the gas is
(A) 3/8 (B) 3/5 (C) 3/4 (D) 2/5
Ans : (B)

The velocity of a car travelling on a straight road is 36 kmh–1 at an instant of time. Now travelling with uniform
acceleration for 10 s, the velocity becomes exactly double. If the wheel radius of the car is 25 cm, then which of the
following numbers is the closest to the number of revolutions that the wheel makes during this 10 s?
(A) 84 (B) 95 (C) 126 (D) 135
Ans : (B)
Two glass prisms P1
and P2 are to be combined together to produce dispersion without deviation. The angles of the
prisms P1 and P2 are selected as 4° and 3° respectively. If the refractive index of prism P1 is 1.54, then that of P2 will
be
(A) 1.48 (B) 1.58 (C) 1.62 (D) 1.72
Ans : (D)

The ionization energy of the hydrogen atom is 13.6 eV. The potential energy of the electron in n = 2 state of hydrogen
atom is
(A) + 3.4 eV (B) – 3.4 eV (C) + 6.8 eV (D) – 6.8 eV
Ans : (D)

Two spheres of the same material, but of radii R and 3R are allowed to fall vertically downwards through a liquid of
density σ. The ratio of their terminal velocities is
(A) 1 : 3 (B) 1 : 6 (C) 1 : 9 (D) 1 : 1
Ans : (C)
