Question

Which of the statements below is NEVER true?

(a) If a negative charge is shot into a uniform electric field is will move what a constant non-zero acceleration through the field.

(b) If the electric field at a point is zero, then the electric potential at the point is also zero.

(c) If a negatively charged particle is placed at rest near the South pole of a permanent magnet it will be attracted to the magnet.

(d) If a charged particle is moving perpendicular to a uniform magnetic field it is moving with a constant magnitude acceleration.

(e) If the net force on a charge moving in a uniform magnetic field is non-zero the charge's kinetic energy is constantly changing.

(a) If a negative charge is shot into a uniform electric field is will move what a constant non-zero acceleration through the field.

this can be true , if theta = 0 degree

(b) If the electric field at a point is zero, then the electric potential at the point is also zero.

this can be true.

(c) If a negatively charged particle is placed at rest near the South pole of a permanent magnet it will be attracted to the magnet.

this can be true

as the magnetic force is zero when the charge is at rest

(d) If a charged particle is moving perpendicular to a uniform magnetic field it is moving with a constant magnitude acceleration.

this is true

(e) If the net force on a charge moving in a uniform magnetic field is non-zero the charge's kinetic energy is constantly changing.

as the magnetic force is always perpendicular to motion of the charge.

the kientic energy will be constant
