Physics · Force on a moving charge in uniform magnetic and electric fields
Particles having positive charge occasionally come with high velocity from the s
Particles having positive charge occasionally come with high velocity from the sky towards the earth on account of magnetic field of earth, they would be deflected towards:
- A. North
- B. South
- C. \) East
- D. west
Step-by-step solution
A positively charged particle moving downward (toward Earth) experiences a Lorentz force F = q(v × B). In Earth's magnetic field, the horizontal component points north (in the northern hemisphere). Using the right-hand rule: downward velocity (v) cross northward magnetic field (B) gives a force directed eastward. Thus, the particle deflects east.
