plz friends answer it fast urgent !!!​

Answer 1

let CD be x

Initial KE = 0.06

Final = 0

Initial potential = 2k(5)(-5)× 10^-12/3

final = 2k (5)(-5)× 10^-12/√9 + x^2

Total initial Energy = 0.06 - 50k × 10^-12/3

= 0.06 - 50× 9× 10^9× 10^-12/3

= 0.06 - 150× 10^-3

= 0.06 - 0.15

= -0.09

Total final Energy = -50k× 10^-12/√9 + x^2

= -50× 9× 10^9× 10^-12/√9 + x^2

= -450× 10^-3/√9 + x^2

= -0.45 /√9 + x^2

0.09 = 0.45 /√9 + x^2

1/5 = 1/√9 + x^2

25 = 9 + x^2

x^2 = 16

x= 4
