A capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has radius 10.5 cm,

Step2247 [10]

Answer:

$U = 2.91 *10^{-5} J$

Explanation:

energy density can be obtained as

$U = \frac{1}{2}\epsilon_o E^{2}$

Where,

E is electric field $= \frac{kQ}{R^{2}}$

K COLOUMB CONSTANT =8.99*10^{9} N -m2 /C2

Q is charge = CV

C is capacitance = $4\pi \epsilon_o \frac{r_1 r_2}{r_2 -r_1}$

$=4\pi *8.85*10^{-12} [\frac{10.5*16.5}{16.5 -10.5}]$

$= 3.21*10^{-9} F$

$Q = 3.21*10^{-9} *150 = 4.81*10^{-7] C$

for r = 10.6 cm

$E = \frac{8.99*10^{9}*3.21*10^{-9}}{0.106^{2}}$

E = 2568.34 N/C

$U = \frac{1}{2}\epsilon_oE^{2}$

$U = \frac{1}{2}*8.85*10^{-12} *2568.34 ^2$

$U = 2.91 *10^{-5} J$

Suppose that you are taking a course in geometry. You are trying to determine whether two geometric shapes are identical, so you

Nataly_w [17]

Explanation:

Yes, in order to determine whether two geometric figures are identical or not we tend to rotate one of the figure clockwise or anti clock wise mentally. However, in clockwise rotation larger the angel more will be the time taken for instance, it will take longer to rotate 120° than to rotate 40°. Whereas in anti clockwise ration it will be vice versa.
