The diameter of an atom is approximately MCQ with Answer and Explanation

The diameter of an atom is approximately
A. 10⁻⁶ m
B. 10⁻¹⁵ m
C. 10⁻³ m
D. 10⁻¹⁰ m
Answer: Option D
Solution (By JKSSB Mock Tests)
Atomic diameter ~ 1 Å = 10⁻¹⁰ m. Nucleus is 10⁻¹⁵ m (femtometre). Atomic size determined by electron cloud. 10⁻⁶ m is typical cell size. 10⁻³ m is millimetre.

Question #1
Momentum conservation follows from:
A. Newton's first law
B. Newton's second law
C. Energy conservation
D. Newton's third law

Correct Answer: Option D


Explanation:
Internal forces cancel in pairs (third law), so net external force = 0 ⇒ dp/dt = 0 (second law) ⇒ momentum constant. Memory aid: 'Momentum conservation ⇔ no external force ⇔ action-reaction pairs'. Mechanics foundation frequently tested in competitive exams.

Question #2
Two objects of masses 1 kg and 4 kg have equal momentum. What is the ratio of their kinetic energies?
A. 1:2
B. 2:1
C. 1:4
D. 4:1

Correct Answer: Option D


Explanation:
Kinetic Energy (K) is related to momentum (p) by the formula K = p² / 2m. Since they have equal momentum, p is constant. Therefore, K is inversely proportional to mass (K ∝ 1/m). Ratio of kinetic energies K1/K2 = m2/m1 = 4/1 = 4:1. The lighter object has more kinetic energy.

Question #3
If an object is placed at the center of curvature of a concave mirror, the image formed is:
A. Real, inverted, and magnified.
B. Virtual, erect, and diminished.
C. Virtual, erect, and magnified.
D. Real, inverted, and of the same size.

Correct Answer: Option D


Explanation:
For a concave mirror, when an object is placed exactly at the center of curvature (C), the image is also formed at C. The image is real (can be captured on a screen), inverted (upside down), and exactly the same size as the object. Magnification in this specific case is exactly -1.
