Topic: Magnetic Effects of Current
Subtopic: Force Acting on Moving Charges
An electron moves in the plane of the page through two regions of space along the
dotted-line trajectory shown in the figure. There is a uniform electric field in Region-I directed
into the plane of the page (as shown). There is no electric field in Region-II. What is a
necessary direction of the magnetic field in regions I and II ? Ignore gravitational forces.

Region-I Down the plane of the page Region-II Up the plane of the page
Region-I Up the plane of the page
Region-II Into the plane of the page
Region-I Up the plane of the page Region-II Out of the plane of the page
Region-I Down the plane of the page Region-II Out of the plane of the page
