Question Report Error

A body weighs 100 N on Earth's surface. Weight at a height equal to Earth's radius is

A. 25 N

B. 100 N

C. 50 N

D. 0 N

Answer: Option A

Solution (By JKExamLibrary)

g' = g (R/(R+h))² = g (1/2)² = g/4. Weight = 100/4 = 25 N.

Polarization proves light is:

A. Longitudinal wave

B. Mechanical wave

C. Transverse wave

D. Matter wave

View Answer & Solution Discuss

Correct Answer: Option C

Explanation:
Polarization possible only for transverse waves (oscillations ⊥ propagation). Longitudinal waves (sound) cannot be polarized. Memory aid: 'Polarization ⇒ transverse nature; light is EM transverse wave'. Wave property frequently tested in competitive exams.
