Question

A negative charged particle of known magnitude q is placed in a uniform electric field of known strength E. What additional information is needed to determine the magnitude of the force on the particle?
a. The distance between the charged plates producing the uniform field.
b. The distance from the nearest plate to the charged particle.
c. The magnitude of the charges producing the field.
d. The mass of the negatively charged particle.
d. No additional information is needed.

Answer 1

Answer:d

Explanation:

Electric field is a region around charged particle where charged particle experience a force .

Magnitude of Force experienced by charged particle is given by

$F=q\cdot E$

where F=force experienced by charged particle

q=charge of particle

E=strength of electric field

If q and E are given then no additional information is needed to determine the magnitude of force.
