Chapter 31: Q. 1 (page 901)

The figure shows the electric and magnetic fields in frame A. A rocket in frame B travels parallel to one of the axes of the A coordinate system. Along which axis must the rocket travel, and in which direction, in order for the rocket scientists to measure (a) $B_{B} > B_{A}$ (b) $B_{B} = B_{A}$ and (c) $B_{B} < B_{A}$ ?

Short Answer

Expert verified

(a) $B_{B} > B_{A}$ : Along the -X direction.

(b) $B_{B} = B_{A}$ : Along either +Y axis or -Y axis.

Step by step solution

Part (a) Step 1 : Given information:

We have given that $B_{B} > B_{A}$

Part (a) Step 2 : Explanation

It is known that: $\overset{鈫�}{E} = \overset{鈫�}{v} 脳 \overset{鈫�}{B}$ .For $B_{B} > B_{A}$ ; The direction of the electric field in the figure is upward. To make the larger magnetic field in frame B, The rocket must travel perpendicular to $\overset{鈫�}{E_{A}}$ . The rocket will travel along negative X direction.

Part (b) Step 1: Given information:

We have given that $B_{B} = B_{A}$

Part (b) Step 2: Explanation:

In order to calculate $B_{B} = B_{A}$ ; The rocket must travel parallel to the direction of the electric field. Therefore, along the positive or negative Y axes.

Part (c) Step 1: Given information:

We have given that $B_{B} < B_{A}$

Part (c) Step 2: Explanation:

To calculate $B_{B} < B_{A}$ , Keeping in mind the upward direction of the magnetic field; The rocket must travel perpendicular to $\overset{鈫�}{E_{A}}$ and away from it. Therefore, Along the Positive X axis.
