Respuesta :

A negatively charged particle is at rest in a region where a uniform magnetic field points in the positive x direction and a uniform electric field points in the positive y direction.

The correct option is (B)The vector sum of the forces is initially in the negative y direction.

What is a uniform magnetic field?

Equally spaced parallel straight lines represent a uniform magnetic field. A tiny magnet's north-seeking pole can be used to determine the flux's direction.

The flux lines are continuous and form complete loops. In the area that forms the equilateral triangle with side A, a uniform magnetic field is present. The triangle's plane and the magnetic field are mutually perpendicular.
