Pendulum on planet with g' = 4g. Period becomes: MCQ with Answer and Explanation

Pendulum on planet with g' = 4g. Period becomes:
A. Double
B. Same
C. Four times
D. Half
Answer: Option D
Solution (By JKExamLibrary)
T ∝ 1/√g. If g' = 4g, T' = T/√4 = T/2. Higher gravity ⇒ faster oscillations. Memory aid: 'Pendulum: T ∝ 1/√g; 4× gravity ⇒ half period'. Oscillations proportionality frequently tested in competitive exams.

Question #3 Report Error
The defect of vision in which a person cannot see nearby objects clearly is
A. Myopia
B. Presbyopia
C. Hypermetropia
D. Astigmatism

Correct Answer: Option C


Explanation:
Hypermetropia (farsightedness): near point farther away, difficulty seeing close objects. Corrected with convex lens. Myopia: distant objects blurry. Presbyopia due to aging. Astigmatism due to irregular cornea.
