A long, straight, horizontal wire carries a left-to-right current of 40 A. If the wire is placed in a uniform magnetic field of

sladkih [1.3K]

Answer:

The magnitude of the resultant of the magnetic field is $4.11\times10^{-5}\ T$

Explanation:

Given that,

Current = 40 A

Magnetic field $B=3.7\times10^{-5}\ T$

Distance = 22 cm

We need to calculate the magnetic field

Using formula of magnetic field

$B'=\dfrac{\mu_{0}I}{2\pi r}$

Where, r = distance

I = current

Put the value into the formula

$B'=\dfrac{4\pi\times10^{-7}\times20}{2\pi\times0.22}$

$B'=1.8\times10^{-5}\ T$

We need to calculate the magnitude of the resultant of the magnetic field

Using formula of resultant

$B''=\sqrt{B^2+B'^2}$

Put the value into the formula

$B''=\sqrt{(3.7\times10^{-5})^2+(1.8\times10^{-5})^2}$

$B''=4.11\times10^{-5}\ T$

Hence, The magnitude of the resultant of the magnetic field is $4.11\times10^{-5}\ T$

The figure shows five electric charges. Four charges with the magnitude of the charge 2.0 nC form a square with the size a = 4.0

bearhunter [10]

Considering the four electric charges forming a square with magnitude of charge of 2.0 nC on each. :

A) Magnitude of the force on the 5.5 nC charge in the middle of the figure = 3.48 * 10^-4 N

B) Direction of the force on the 5.5 nC charge in the middle of the figure = Leftward ( negative x -axis )

Using the given data :

size of square = 4 cm

magnitudes of four charges = 2.0 nC

a) magnitude of the force on the center charge

Electric force between two point charges = $F = \frac{1}{4\pi *E_{o} } \frac{q1q2}{r^2}$ ----- ( 1 )

where ; $\frac{1}{4\pi E_{o} } = 9 * 10^9 Nm^2/C^2$

step 1 ; find r ( distance between charges )

r² = ( 2 )² + ( 2 )² = 8 cm²

back to equation 1

F = 9 * 10⁹ * $\frac{2 * 10^{-9} * (5.5 * 10^{-9}) }{8*10^{-4} }$ = 1.23 * 10^-4 N

∴ magnitude of the force on the center charge ( Fnet )= 4F cos 45°

= 4 * ( 1.23 * 10^-4 ) * $\frac{1}{\sqrt{2} }$ = 3.48 * 10^-4 N

b) The direction of the force at the center is along the negative x-axis ( leftward )
