- A
All charged particles experience the same force
- B
All charged particles move with the same velocity
- C
All electric field lines are directed towards positive charges
- D
All electric field lines are parallel
In case of the uniform electric field, the two electric field lines are
1. straight
2. parallel
3. equidistant
A uniform electric field is a field in which the value of the field strength remains the same
In a uniform electric field, the force experienced by a charged particle depends on the charge of the particle (q) and the electric field strength (E). The force (F) is calculated using F = qE, meaning particles with different charges experience different forces. Thus, this option is incorrect.
Charged particles in a uniform electric field experience acceleration proportional to their charge-to-mass ratio (q/m), but this does not guarantee the same velocity. Initial velocity, exposure time, and other forces affect their actual velocities. Therefore, this option is incorrect.
Electric field lines originate from positive charges and terminate at negative charges. In a uniform field, lines are straight and parallel, not necessarily directed towards positive charges. Therefore, this option is incorrect.
In a uniform electric field, electric field lines are parallel, straight, and evenly spaced, indicating uniform strength and direction. Therefore, this option is correct.
