A spherical shell of radius Ra carries a total charge qa uniformly distributed on its surface. A larger spherical shell of radiu
mylen [45]

Answer:

Explanation:

Part a)

For a position of point inside the inner shell we can use Gauss law as

\int E. dA = \frac{q}{\epsilon_0}

now here we know that enclosed charge in the inner shell is ZERO

so we have

\int E. dA = 0

E = 0

Now for the position between two shells

r_a< r< r_b

again by Gauss law

\int E. dA = \frac{q}{\epsilon_0}

now here we know that enclosed charge between two shells is given as

q = q_a

so we have

\int E. dA = \frac{q_a}{\epsilon_0}

E = \frac{q_a}{4\pi \epsilon_0 r^2}

Now for position outside the shell we will have

r > r_b

again by Gauss law

\int E. dA = \frac{q}{\epsilon_0}

now here we know that enclosed charge given as

q = q_a + q_b

so we have

\int E. dA = \frac{q_a + q_b}{\epsilon_0}

E = \frac{q_a + q_b}{4\pi \epsilon_0 r^2}

Part b)

If outside the shell net electric field is zero

then we can say

q_a + q_b = 0

q_a = 6 nC

q_b = - 6nC

Part c)

The seeds were sown (change the voice)​
MaRussiya [10]

Answer:

He sowed the seeds

Explanation:

While the question should have given the person who did the sowing for example the seeds were sown by him/ her/ the farmer/ or any name. Therefore, voice is given in passive and to change passive voice to active voice then the sentence will read as follows assuming that the seeds were sown by him

He sowed the seeds

A cross-country skier can complete a 7.5 km race in 45 min. What is the skier’s average speed?
kap26 [50]

Answer:

Speed = 10 km/hr

Explanation:

Speed = Distance / Time

Since we have to convert it into minutes to hours ( because it is km/hr )

45 minutes = 0.75 hours

Therefore,

Speed = 7.5 / 0.75

           = <u>10 km/hr </u>

<u></u>

<u>Hope it helps!</u>
