19.52 32 Part B \" negative Part C Find the pC

Solution

A] Here, kq/r1^2 = E1 and kq/r2^2 = E2

(r2/r1)^2 =E1/E2 = 10/17

(x-10)/(x-5) = sqrt (10/17) = 0.767

x-10 = 0.767*(x-5)

x = 26.46 cm answer

C] E1= kq/r1^2

10 = 9e9*q/(0.2646-0.05)^2

q = 10*(0.2646-0.05)^2/9e9 = 5.12*10^-11 C

= 51.2 pC answer
