For initial Mechanical energy

Where  and vrelative =5 m/s

= 25 + 25 = 50
For final Mechanical energy
When there is maximum extension relative velocity between block = 0

NATA Mock Test - 4 - Question 4

An electromagnetic wave of frequency f = 7.3MHz passes from a vacuum into a dielectric medium with permittivityε = 9. Then,

Detailed Solution for NATA Mock Test - 4 - Question 4

As permittivity is greater than the permittivity of free space so the refractive index of medium is

Wavelength of the electromagnetic wave in medium will be 
Velocity of wave will be. 

NATA Mock Test - 4 - Question 5

Hence, correct answer is (c)

NATA Mock Test - 4 - Question 11

There are two balls in an urn whose colours are not known (each ball can be either white or black). A white ball is put into the urn. A ball is drawn from the urn. The probability that it is white is

Detailed Solution for NATA Mock Test - 4 - Question 11

Let E(0 < i < 2) denote the event that urn contains 'i' white and '(2 – i)' black balls.
Let A denote the event that a white ball is drawn from the urn.
We have P(Ei) = 1/3 for i = 0, 1, 2 
P (A|E1) = 1/3, P(A|E2) = 2/3, P(A|E3) = 1.
By the total probability rule,
P(A)= P(E1)P(A|E1) + P(E2)P(A|E2) + P(E3)P(A|E3)

NATA Mock Test - 4 - Question 12

The plane passing through the point (−2, −2, 2) and containing the line joining the points
(1, 1, 1) and (1, −1, 2) makes intercepts on the coordinates axes the sum of whose lengths is

Detailed Solution for NATA Mock Test - 4 - Question 12

Equation of any plane passing through (−2, −2, 2) is 
a(x + 2) + b(y + 2) + c(z – 2) = 0
Since it contains the line joining the points (1, 1, 1) and (1, −1, 2), it contains these points as well
so that
3a + 3b – c = 0
and 3a + b + 0 = 0
Solving we get

and thus the equation of the plane is
(x + 2) - 3(y + 2) = 0
x+3y-4=0

Intercepts on axes = 4, 4/3
The required sum= 4+(4/3)=16/3

NATA Mock Test - 4 - Question 13

If a, b, c are in GP and  are in AP, then a, b, c are the lengths of the sides of a triangle which is

Detailed Solution for NATA Mock Test - 4 - Question 13

a, b, c are in GP b2 = ac
 are in AP.
2(log 2b – log 3c) = log a – log 2b + log 3c – log a
log 2b = log 3c 2b = 3c
∴ b2 = ac & 2b = 3c
 b = 2a/3 and c = 4a/9
Since (a+b) = 5a/3 > c, (b+c) = 10a/9 > a and
(c + a) = 13a/9 > b, therefore, a, b, c are the sides
of a triangle. Also, as ‘a’ is the greatest side, let us
find angle A of ΔABC

Hence ΔABC is an obtuse angled triangle.

NATA Mock Test - 4 - Question 14

1 + 3 + 6 + 10 + 15 + ……………………….n terms is

Detailed Solution for NATA Mock Test - 4 - Question 14

NATA Mock Test - 4 - Question 15

The solution of the equation (2x + y + 1) dx + (4x + 2y – 1) dy = 0 is

Detailed Solution for NATA Mock Test - 4 - Question 15

Put 2x + y = X ⇒Therefore, the given equation is reduced to

 = x + constant
2(2x + y) + log (2x + y – 1) = 3x + constant
x + 2y + log (2x + y – 1) = C
