CBSE BoardEnglish MediumSTD 12 SciencePhysics5. Magnetism and matter1 Mark
MCQ
Due to the earth's magnetic field, charged cosmic ray particles
  • A
    Can never reach the equator
  • B
    Require less kinetic energy to reach the equator than the poles
  • ✓
    Require greater kinetic energy to reach the equator than the poles
  • D
    Can never reach the poles
✓

Answer

Correct option: C.
Require greater kinetic energy to reach the equator than the poles
c
The earth's magnetic field is strongest at the poles hence cosmic rays of charges particles are deflected away from the equator. In order to reach the equator, they need to posses greater Kinetic Energy
