Chapter 31: Q. 28 (page 902)

What are the electric field strength and direction at the position of the electron in FIGURE $P 31.28$ $?$

Short Answer

Expert verified

Electric field strength in figure $P 31.8$ is $1.75 \times 10^{6} V / m$ , $F_{E_{}}$ isrole="math" localid="1648932697397" $2.8 \times 10^{- 13} N$ and $F_{B}$ is $1.6 \times 10^{13} N$

Step by step solution

Figure for direction of electric field intensity is depicted.

Figure is,

The figure on the page has come to an end is,

Calculation for force

Magnetic and electric fields both produce force:

$\tan (30 °) = \frac{F_{B}}{F_{E}}$

A magnetic force occurs upward when utilizing the right hand rule.

$F_{B} = qvB$

$F_{B} = 1.6 \times 10^{- 19} \times 10^{7} \times 0.1$

$F_{B} = 1.6 \times 10^{- 13} N$

For $F_{E}$ :

$\tan (30 °) = \frac{F_{B}}{F_{E}} = \frac{1.6 \times 10^{13}}{F_{E}}$

$F_{E} = \frac{1.6 \times 10^{- 13}}{0.57}$

$F_{E} = 2.8 \times 10^{- 13} N$

Calculation for electric field strength

Strength of the electric field,

$F_{E} = qE$

$E = \frac{F_{E}}{q}$

$F_{E}$ -Force of electric field

$q$ -charge

$E = \frac{2.8 \times 10^{- 13}}{1.6 \times 10^{- 19}}$
