CUET UG 2025 Physics Question Paper (May 13, 2025) (Shift 2)

Question 1

If the protons and electrons are the only basic charges in the universe, all the observable charges have to be integral multiples of e. Thus, if an object contains x electrons and y protons, the net charge on the object will be

Accepted Answer

(y - x) e

Answer

- (x + y) e

Answer

(x + y) e

Answer

(x - y) e

Question 2

A charge of magnitude $3 	imes 10^{-7}$ C is located at a distance of 0.09 m from a point P. Obtain the work done in bringing a charge of $2 	imes 10^{-9}$ C from infinity to the point P.

Accepted Answer

$6 	imes 10^{-5}$ J

Answer

$6 	imes 10^4$ J

Answer

$6 	imes 10^{-2}$ J

Answer

$6 	imes 10^5$ J

Question 3

In a series combination of capacitors connected across a battery

Accepted Answer

each capacitor has equal charge for any value of its capacitance

Answer

each capacitor has an equal charge for certain values of capacitances only

Answer

each capacitor has different charge for a certain value of its capacitance

Answer

each capacitor has different charge for any value of its capacitance

Question 4

Two point charges, $4 \mu$C and $-3 \mu$C (with no external field) are placed at (-6 cm, 0, 0) and (6 cm, 0, 0), respectively. The amount of work required to separate the two charges infinitely away from each other will be

Accepted Answer

0.9 J

Answer

0.18 J

Answer

-0.9 J

Answer

-0.018 J

Question 5

If the net flux through a cube is $1.05 	ext{ N m}^2 	ext{ C}^{-1}$, what will be the total charge inside the cube? (Given: The permittivity of free space is $8.85 	imes 10^{-12} 	ext{ C}^2 	ext{ N}^{-1} 	ext{ m}^{-2}$).

Accepted Answer

$9.29 	imes 10^{-12}$ C

Answer

$9.29 	imes 10^{-11}$ C

Answer

$9.27 	imes 10^{-10}$ C

Answer

$9.22 	imes 10^{-6}$ C
