Can you provide me question papers of ISAT?

[Raman Vij]

ISAT Entrance Exam conducted for admission in the B. Tech. Courses offered by the IIST-Indian Institute of Space Science & Technology .

Here I am providing some questions related to the ISAT exam

1. A projectile is fired at an angle 60◦ with some velocity u. If the angle is changed infinitesimally, let the
corresponding fractional changes in the range and the time of flight be x and y, respectively, Then y is
(A) 2
3x
(B) −2
3x
(C) 2x
(D) −2x
2. A ball is dropped down vertically from a tall building. After falling a height h it bounces elastically
from a table inclined at an angle θ and hits a wall at a distance d from the point of earlier impact
horizontally, then

h
d
(A) θ = (1/2) sin−1(2d/h)
(B) θ = (1/2) tan−1(d/h)
(C) θ = (1/4) sin−1(d/h)
(D) θ = (1/2) tan−1(2d/h)
3. A photon with an initial frequency 1011Hz scatters off an electron at rest. Its final frequency is
0.9×1011 Hz. The speed of the scattered electron is close to (h = 6.63×10−34 Js, me = 9.1×10−31 kg)
(A) 4 × 103 ms−1
(B) 3 × 102 ms−1
(C) 2 × 106 ms−1
(D) 30ms−1
4. Let a particle have an instantaneous position ~r(t), velocity ~v(t) and acceleration ~a(t). Necessary conditions
for it to be considered as an instantaneous circular motion about the origin are
(A) ~r.~v = 0 ; ~a.~v = 0 ; ~a.~r < 0
(B) ~r.~v = 0 ; ~a.~v = 0 ; ~a.~r > 0
(C) ~r.~v > 0 ; ~a.~v = 0 ; ~a.~r = 0
(D) ~r.~v = 0 ; ~a.~v > 0 ; ~a.~r < 0
5 A large parallel plate capacitor is made of two metal plates of size 2m × 1m. It has a dielectric slab
made of two dielectrics of permeability K1 and K2 as shown in the figure, the distance between them
being 0.1m . It is charged by a battery of 1000V after which the battery is disconnected. Now the
dielectric slab is pulled out by 10cm. The work done in doing so is (ignore the gap between the plates
and the dielectric slab)

K = 2 K =3 1 2 0.1m
1m 1m
(A) 2.5 × 105ǫ0 J
(B) −2.5 × 105ǫ0 J
(C) 5 × 105ǫ0 J
(D) −5 × 105ǫ0 J
