A person with myopia uses spectacles of power -2 D. Far point without glasses is MCQ with Answer and Explanation

A person with myopia uses spectacles of power -2 D. Far point without glasses is

A. 25 cm

B. 2 m

C. Infinity

D. 50 cm

Answer: Option D

Solution (By JKExamLibrary)

For myopia, corrective lens forms image of distant object at far point. 1/f = 1/(-far point) - 1/(-∞) => -2 = -1/F => F = 0.5 m = 50 cm.

The Chandrasekhar Limit is a fundamental concept in astrophysics that determines the ultimate fate of a star. It is specifically defined as the maximum mass of a:

A. Red Giant

B. White Dwarf

C. Black Hole

D. Neutron Star

View Answer & Solution Discuss

Correct Answer: Option B

Explanation:
Subrahmanyan Chandrasekhar calculated that a White Dwarf star cannot support itself against gravitational collapse if its mass exceeds approximately 1.44 times the mass of our Sun. This is the Chandrasekhar limit. Stars above this mass limit will eventually collapse further into a dense neutron star or a black hole.

Uniform acceleration: v-t graph is:

A. Horizontal line

B. Hyperbola

C. Parabola

D. Straight line with slope

View Answer & Solution Discuss

Correct Answer: Option D

Explanation:
a = constant ⇒ v = u + at (linear in t). Slope = acceleration. Memory tip: 'v-t slope = acceleration; area = displacement'. Graph interpretation frequently tested in competitive kinematics sections.
