SOLUTIONS

PHYSICS

1)

When a vector is displaced parallel to itself, neither its magnitude nor its direction changes.

6)

Magnitude of unit vector is one

8) Let ,

Unit vector along

Required vector

Option (2).

9) sinθ =
θ = 30°
between and
180° – 30° = 150°

10)

i = neA Vd

Vd =

11) Vd ∝ E

12)
R= and Volume = Aℓ

R= ⇒ℓ=

13)
put ℓ = 1 cm
A = 1 cm × 100 cm

14)

100 = R0 [1 + α (100 – 0)] .....(1)


200 = R0 [1 + α (T – 0)] .....(2)

1 + Tα = 2 + 200α
α(T – 200) = 2 – 1

T – 200 =
T = 400°C

16)
Current density J = σE

or

or

17)
So, RXY = 15 Ω

19)

(i) Equivalent circuit when the equivalent resistance is calculated between points P and Q.
RPQ =
(ii) Equivalent circuit when the equivalent resistance is calculated between points Q and R

RQR =
(iii) Equivalent circuit when the equivalent resistance is calculated between points P and R.

RPR =

23)

y = ex sin x

24)

v = 3t2 – 3t + 1

For vmin : -

→ minima

26)

= =π
27)

28) Acceleration is downwards, therefore, pseudo force will act upwards.


Reading = m(g – a) = 5 × (10 – 2) = 40 N

29)

Velocity at the time of striking the floor,

Velocity with which it rebounds

∴ Change in velocity Δv = 7 – (–14) = 21 m/s

∴ Acceleration =
= 2100 m/s2 (upwards)

30)

g=0

34)

2g = 3(g – a) ⇒

35) Force F =

= = 1500 N

37)

47)
48)

1200 v = 24 × 104

49) Area under (F–t) curve = M(vf – vi)


or 50 × 5 + 75 × 5 = 16(vf – 0)
∴ vf = 39 m/s.

50)

p = at – bt2

F= = a – 2bt = 0

CHEMISTRY

61) n = 3, ℓ = 1, ⇒ 1 orbital

62) Orbital angular momentum =

for d-orbital ℓ = 2,
The Orbital angular momentum
=
=

67)
At an angle of 45° from x & y axis

72) Decreasing order of functional group (priority)


90)

96) In homologous functional group is same, given compounds are functional isomer because
functional group is different.
