Sample questions from this chapter

How do two stationary point charges of the same sign interact?
  1. They repel each other ✓
  2. They attract each other
  3. They exert no force on each other
  4. They alternately attract and repel
Answer: A. Coulomb force is repulsive for like charges and attractive for unlike charges.
Why not B: Attraction occurs between charges of opposite signs.
Why not C: Each charge creates an electric field that acts on the other.
Why not D: The electrostatic force direction does not oscillate for stationary charges.
Two point charges +2.00 μC and +3.00 μC are 0.300 m apart in vacuum. Using k=9.00×10⁹ N m² C⁻², what is the force magnitude?
  1. 0.200 N
  2. 1.80 N
  3. 0.600 N ✓
  4. 6.00 N
Answer: C. F=kq₁q₂/r²=(9.00×10⁹)(2.00×10⁻⁶)(3.00×10⁻⁶)/(0.300)²=0.600 N.
Why not A: This divides the correct numerator by three times the required squared distance factor.
Why not B: This is three times the result from kq₁q₂/r².
Why not D: This shifts the decimal one place above the Coulomb-law result.
What is the electric field at any interior point of a uniformly charged thin spherical shell?
  1. Zero ✓
  2. kQ/r² directed outward
  3. kQ/R² directed inward
  4. σ/ε₀ directed outward
Answer: A. A concentric Gaussian surface inside the shell encloses zero charge; spherical symmetry then requires E=0.
Why not B: A Gaussian sphere inside encloses no shell charge, so the point-charge expression does not apply.
Why not C: The nonzero surface field cannot be assigned throughout the empty interior.
Why not D: This resembles a conductor boundary result and is not the interior field.

Questions

How many NEET questions are there on Electric Charges and Fields?

This chapter test has 30 questions — 10 easy, 14 medium and 6 hard — all written against the NCERT Class 12 chapter.

Is this NEET Physics chapter test free?

Yes. Every chapter test is free with no login, and you get your all-India rank on every one. Nothing on the site is on sale right now.

Do the questions explain the wrong options?

Yes — every distractor carries its own explanation naming the specific misconception that makes a student pick it. That is the part most question banks skip, and it is the part that changes your next attempt.
