Chapter 19, Problem 1CQ

a)

To determine

The direction of the magnetic force.

Answer to Problem 1CQ

$-y$

Explanation of Solution

The magnetic force on a moving charged particle is given by,

$\overrightarrow{F}=q\left(\overrightarrow{v}\times \overrightarrow{B}\right)$

The velocity is directed along $+x$ and the magnetic field is along $+z$ axis. Hence using right hand thumb rule, the direction of the force will be $-y$.

Conclusion: The direction of the magnetic force will be $-y$.

b)

To determine

The direction of the magnetic force.

Answer to Problem 1CQ

$+y$

Explanation of Solution

The magnetic force on a moving charged particle is given by,

$\overrightarrow{F}=q\left(\overrightarrow{v}\times \overrightarrow{B}\right)$

The velocity is directed along $+x$ and the magnetic field is along $-z$ axis. Hence using right hand thumb rule, the direction of the force will be $+y$.

Conclusion: The direction of the magnetic force will be $+y$.

c)

To determine

The direction of the magnetic force.

Answer to Problem 1CQ

$+z$

Explanation of Solution

The magnetic force on a moving charged particle is given by,

$\overrightarrow{F}=q\left(\overrightarrow{v}\times \overrightarrow{B}\right)$

The velocity is directed along $+x$ and the magnetic field is in the $xy$ plane. Hence using right hand thumb rule, the direction of the force will be $+z$.

Conclusion: The direction of the magnetic force will be $+z$.

d)

To determine

The direction of the magnetic force.

Answer to Problem 1CQ

$-y$

Explanation of Solution

The magnetic force on a moving negatively charged particle is given by,

$\overrightarrow{F}=-q\left(\overrightarrow{v}\times \overrightarrow{B}\right)$

The velocity is directed along $+x$ and the magnetic field is along $+z$ axis. Hence using right hand thumb rule, the direction of the force will be $+y$.

Conclusion: The direction of the magnetic force will be $-y$.

e)

To determine

The direction of the magnetic force.

Answer to Problem 1CQ

$-y$

Explanation of Solution

The magnetic force on a moving negatively charged particle is given by,

$\overrightarrow{F}=-q\left(\overrightarrow{v}\times \overrightarrow{B}\right)$

The velocity is directed along $+x$ and the magnetic field is along $+z$ axis. Hence using right hand thumb rule, the direction of the force will be $+y$.

Conclusion: The direction of the magnetic force will be $-y$.

f)
