Answer:
-(1/4πϵ0)Qq/r^2
Step-by-step explanation:
Firstly we have to assume the uniform shell of radius R as point charge as the point charge.
Then apply coulomb equation of electrostatic charge (Fe=q1q2/4πϵ0r2) where the q1 and q2 are point charges and r is the distance from the centre of charges.
But remember there's a condition that r>>R otherwise the charge will get non-uniformely distributed.

Answer:
Helen requires 15$ more to buy the three books.
Step-by-step explanation:
We are given the following in the question:
Cost of dictionary = $7
Cost of dinosaur book = $16
Cost of cook book = $17
Helen's allowance = $25
Total cost of three books =
Extra money required to buy three books =
Thus, Helen requires 15$ more to buy the three books.
For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
You would need 6 quarts of milk. You would do 24(2) then you take 48 and divide it by 288 and you get 6.
