Solved Sample KCET Questions Answers

Q1: If α and β are the roots of the equation x2 = x + 1, then α2+β2 is?

Solution: In the equation:  x2 = x + 1 => x2 - x - 1 = 0,

 α + β = - b/a= 1, and 

αβ = c/a= - 1

So,  α2+β2= (α +β)2-  2αβ 

=> (1)2- 2 (-1) 

=> α2+β2= 3

Q2: If the separation between two plates is 2 cm, and the potential across them is - 10 V & 30 V, respectively, then what will be the electric field between these plates?

Solution: Given d = 2 cm, V1 = - 10 V, V2 = 30 V

We know that E = dV/d

dV = 30 - (- 10) = 40 V, and

d = 2 cm = 2 x 10-2cm

So, E = 400/(2 x 10-2) = 20000 V/m

Q4: We can improve the oil content and quality of groundnut by using the _______technique.

1. Biofortification

2. Biodegradation

3. Biomagnification

4. Bioremediation

Ans: Biofortification technique can be used to improve oil content and groundnut’s quality.

Q5: Which of the following possess net dipole moment?

1. SO2

2. BeCl2

3. BF3

4. CO2

Ans: Among these four options, SO2 has a net dipole moment.

It’s because the SO2 molecule has a bent structure, as we can see in the diagram below:

This is because electrons are as far away from each other as possible.

O2 has a stronger pull on the electron in the bond between S and O. This results in a dipole moment, which can be seen more easily using vectors, as shown in the diagram below:
