A Gaussian surface in the shape of a right circular cylinder with end caps has a radius of 12.5 cm and a length of 112 cm. Throu

gh one end there is an inward magnetic flux of 36.4 μWb. At the other end there is a uniform magnetic field of 2.33 mT, normal to the surface and directed outward. What are the (a) magnitude and (b) direction (inward or outward) of the net magnetic flux through the curved surface?

Answer:

A) Magnitude of flux; Φ_c = 77.97 μWb

B) Direction is inwards

Explanation:

A) The magnetic flux through a closed surface is zero. Thus, the summation of the flux through the two bases and the two bases and the curved surface equals zero and is written as:

Φ_s1 + Φ_s2 + Φ_c = 0

Where;

Φ_s1 is the flux through one end and it's given as; -36.4 μWb

(negative sign denotes the direction which is inwards)

Φ_s2 is the flux through the other end is given by a formula;

Φ_s2 = BA

Area is; A = πr²

Thus; Φ_s2 = Bπr²

We are given;

B = 2.33 mT = 2.33 x 10^(-3) T

r = 12.5 cm = 0.125 m

Thus,

Φ_s2 = 2.33 x 10^(-3) x π(0.125²)

Φ_s2 = 114.37 x 10^(-6) Wb

Thus;

Φ_s2 = 114.37 μWb

Since we know Φ_s1 and Φ_s2, let's plug them into the first equation to find the magnetic flux;Φ_c

Thus;

-36.4 μWb + 114.37 μWb + Φ_c = 0

Φ_c = -77.97 μWb

The magnitude is the absolute value which is;Φ_c = 77.97 μWb

B) Since the flux has a negative value, thus the direction is inwards

A very long uniform line of charge has charge per unit length λ1 = 4.68 μC/m and lies along the x-axis. A second long uniform li
Kitty [74]

Answer:

E_{net} = 6.44 \times 10^5 N/C

Explanation:

As we know that electric field due to infinite line charge distribution at some distance from it is given as

E = \frac{2k \lambda}{r}

now we need to find the electric field at mid point of two wires

So here we need to add the field due to two wires as they are oppositely charged

Now we will have

E_{net} = \frac{2k\lambda_1}{r} + \frac{2k\lambda_2}{r}

now plug in all data

\lambda_1 = 4.68 \muC/m

\lambda_2 = 2.48 \mu C/m

r = 0.200 m

now we have

E_{net} = \frac{2k}{r}(4.68 + 2.48)

E_{net} = \frac{2(9\times 10^9)}{0.200}(7.16 \times 10^{-6})

E_{net} = 6.44 \times 10^5 N/C

A light source radiates 60.0 W of single-wavelength sinusoidal light uniformly in all directions. What is the amplitude of the m
Anna35 [415]

To solve this problem it is necessary to take into account the concepts of Intensity as a function of Power and the definition of magnetic field.

The intensity depending on the power is defined as

I = \frac{P}{4\pi r^2},

Where

P = Power

r = Radius

Replacing the values that we have,

I = \frac{60}{(4*\pi (0.7)^2)}

I = 9.75 Watt/m^2

The definition of intensity tells us that,

I = \frac{1}{2}\frac{B_o^2 c}{\mu}

Where,

B_0 =Magnetic field

\mu = Permeability constant

c = Speed velocity

Then replacing with our values we have,

9.75 = \frac{Bo^2 (3*10^8)}{(4\pi*10^{-7})}

Re-arrange to find the magnetic Field B_0

B_o = 2.86*10^{-7} T

Therefore the amplitude of the magnetic field of this light is B_o = 2.86*10^{-7} T

Capacitor C1 is initially charged to V1 and capacitor C2 is initially charged to V2. The capacitors are then connected to each o
o-na [289]

Answer:

<em>20.08 Volts</em>

Explanation:

<u>Parallel Connection of Capacitors</u>

The voltage across any two elements connected in parallel is the same. If the elements are capacitors, then each voltage is

\displaystyle V_1=\frac{Q_1}{C_1}

\displaystyle V_2=\frac{Q_2}{C_2}

They are both the same after connecting them, thus

\displaystyle \frac{Q_2}{C_2}=\frac{Q_1}{C_1}

Or, equivalently

\displaystyle Q_2=\frac{C_2Q_1}{C_1}

The total charge of both capacitors is

\displaystyle Q_t=Q_1\left(1+\frac{C_2}{C_1}\right)

We can compute the total charge by using the initial conditions where both capacitors were disconnected:

Q_t=V_{10}C_1+V_{20}C_2=25\cdot 24+13\cdot 11=743\ \mu C

Now we compute Q1 from the equation above

\displaystyle Q_1=\frac{Q_t}{\left(1+\frac{C_2}{C_1}\right)}=\frac{743}{\left(1+\frac{13}{24}\right)}=481.95\ \mu C

The final voltage of any of the capacitors is

\displaystyle V_1=V_2=\frac{481.95}{24}=20.08\ V
