AP EAMCET · PHYSICS · Magnetic Effects of Current
In which of the following case no force exerted by a magnetic field on a charge?
- A Moving with constant velocity
- B Moving in a circle
- C At rest
- D Moving along a curved path
Answer & Solution
Correct Answer
(C) At rest
Step-by-step Solution
Detailed explanation
Lorentz force or magnetic force is, F→=qv→×B→ From the above expression, it is clear that the magnetic field acts perpendicular to the instantaneous direction of charge, if there is no velocity component of the charge or charge is at rest then the magnetic…
