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.
This isn't an answer, rather a suggestion. I would use the website desmos to help me. But for future reference I can help you.
f(x) = - x+6 is similar to y=-x+6.
Simply plug in random numbers into the variable x (preferably ones that could fit on your paper like 0,1,2,3...)
Solution D
Just put into a calculator
Hope I helped :)
S= a/4 + 8u
S - 8u = a/4 (First you subtract 8u from both sides)
4(S - 8u) = a ( Then you multiply both sides by 4)
Final answer:
4(S - 8u) = a
Step-by-step explanation:
29+1/5r=
29+(1/5×-1/2)
29+1/10
291/10
=29.1
