Answer:
C1 + C2 = 30 parallel connection
C1 * C2 / (C1 + C2) = 7.2 series connection
C1 * C2 = 7.2 * (C1 + C2) = 216
C2 + 216 / C2 = 30 using first equation
C2^2 + 216 = 30 C2
C2^2 - 30 C2 + 216 = 0
C2 = 12 or 18 solving the quadratic
Then C1 = 18 or 12
Answer:
c. 0.02 C and 4 J
Explanation:
Applying,
Q = CV................ Equation 1
Where Q = Charge, C = Capacitance of the capacitor, V = Voltage.
From the question,
Given: C = 50 μF = 50×10⁻⁶ F, V = 400 V
Substitute these values into equation 1
Q = (50×10⁻⁶)(400)
Q = 0.02 C.
Also Applying
E = CV²/2............. Equation 2
Where E = Energy stored.
Therefore,
E = (50×10⁻⁶ )(400²)/2
E = 4 J
Hence the right option is c. 0.02 C and 4 J

Explanation:
Below is an attachment containing the solution.
G = ![\frac{F_{g} r^{2} }{m_{1} m_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BF_%7Bg%7D%20r%5E%7B2%7D%20%20%7D%7Bm_%7B1%7D%20m_%7B2%7D%20%20%7D)
Explanation:
Solving for G simply implies that we make G the subject of the formula:
Given equation:
F
= G ![\frac{m_{1} m_{2} }{ r^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bm_%7B1%7D%20%20m_%7B2%7D%20%7D%7B%20r%5E%7B2%7D%20%7D)
To make G the subject of this expression follow these steps:
Multiply both sides of the equation by ![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
F
x
= G
x ![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
This gives:
F
= G ![m_{1} m_{2}](https://tex.z-dn.net/?f=m_%7B1%7D%20%20m_%7B2%7D)
Multiply both sides by ![\frac{1}{m_{1} m_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bm_%7B1%7D%20m_%7B2%7D%20%7D)
F
x
=
x G ![m_{1} m_{2}](https://tex.z-dn.net/?f=m_%7B1%7D%20%20m_%7B2%7D)
Therefore:
G = ![\frac{F_{g} r^{2} }{m_{1} m_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BF_%7Bg%7D%20r%5E%7B2%7D%20%20%7D%7Bm_%7B1%7D%20m_%7B2%7D%20%20%7D)
