A moving charged particle is surrounded by?
Correct answer: B. 3 fields
- A. 1 field
- B. 3 fields
- C. 2 fields
- D. 4 fields
Explanation
A moving charged particle is surrounded by three fields:Electric Field: This field arises due to the charge of the particle itself and affects other charges in its vicinity.Magnetic Field: Generated due to the movement of the charge. The interaction between charge and motion creates this field.Gravitational Field: The mass of the particle generates a gravitational field, albeit usually very weak compared to the other two fields.Option A (1 field) is incorrect because it ignores the presence of the magnetic and gravitational fields. Option C (2 fields) is incorrect as it overlooks the gravitational field. Option D (4 fields) is incorrect because there isn't an additional field present beyond the electric, magnetic, and gravitational fields mentioned.

About Charged Particle in a Magnetic Field
A charged particle moving through a magnetic field experiences the Lorentz force, which is perpendicular to both its velocity and the field. The motion may be circular or helical, with questions involving radius, angular frequency, time period, and work done. A stationary charge feels no magnetic force.

The principle of a simple form of mass spectrometer ions is to pass through narrow slits S1 and S2 and into a velocity selector. The ions after passing through the slit S3 are deviated by a uniform magnetic field. The quantities that must remain constant for all ions arriving at the photographic plate are:
An election is projected with a velocity V into a region where there exists a uniform electric field of strength E perpendicular to a uniform magnetic field of directly B. if the electron velocity to remain constant,V must be:
If the direction of initial velocity of the charged particle is neither along nor perpendicular to that of magnetic field then the orbit will be:
A proton is projected with a uniform velocity 'v' along the axis of a current carrying solenoid.
The charged particle is situated in a region of space and it experiences a force only when it is in motion. It can be deduce that the region encloses
