RBSE SS Physics Practice Questions - Rajasthan RBSE Senior Secondary (Class 12) Physics - Code 040 Exam - RBSE SS Physics Practice Questions - Rajasthan RBSE Senior Secondary (Class 12) Physics

Question 1

Two like point charges repel each other with force F when separated by distance r in vacuum. If the separation is doubled, the repulsive force becomes:

F/2 2F 4F F/4

Correct Answer:

F/4

Question 2

Two point charges +3 μC and −2 μC are placed 2 m apart in vacuum. The magnitude of the electrostatic force between them is (k = 9×10^9 N m^2 C^−2):

1.35×10^−2 N 2.7×10^−2 N 6.75×10^−3 N 1.35×10^−3 N

Correct Answer:

1.35×10^−2 N

Question 3

Electric field intensity at a point is defined as the electrostatic force experienced by a:

unit magnetic pole placed at that point unit positive charge placed at that point unit negative charge placed at that point unit mass placed at that point

Correct Answer:

unit positive charge placed at that point

Question 4

The electric field due to a point charge of 2 μC at a distance of 3 m in vacuum is (k = 9×10^9 SI units):

2×10^4 N/C 9×10^3 N/C 2×10^3 N/C 6×10^3 N/C

Correct Answer:

2×10^3 N/C

Question 5

Charges +q and +4q are fixed 30 cm apart. A third charge is placed on the line joining them so that the net force on it is zero. Its distance from +q is:

20 cm (between the charges) 6 cm (between the charges) 15 cm (midpoint) 10 cm (between the charges)

Correct Answer:

10 cm (between the charges)
