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:
t = (M/K)-r
Step-by-step explanation:
We want to isolate the variable t.
So, we should first divide both sides by K
M/K=(t+r)
Then, we can subtract r from both sides, giving us
(M/K)-r=t
And that's your answer
Y = kx
@ y = 216, x = 2
k = y/x = 216/2 = 108
@ x=7
y = (108)(7) = 756
y = quantity, for example:
I want to buy 1 bracelet =
1×7 = 7 + 1 = 8$ per bracelet
Answer:
x = 5
Step-by-step explanation:
The 2 strokes through XM and MY indicate the segments are congruent, so
YM = MX , that is
8x - 24 = 3x + 1 ( subtract 3x from both sides )
5x - 24 = 1 ( add 24 to both sides )
5x = 25 ( divide both sides by 5 )
x = 5
