Find the change in the nucleus, electric potential and electric po joules. HINT (a) change in electric potential (in V)

Explanation / Answer

potential at the location of 8uC,

V = k q1 / r1 + kq2 / r2

V = (9 x 10^9 x 2 x 10^-6 / 0.03) + (9 x 10^9 x 4 x 10^-6 / sqrt(0.03^2 + 0.06^2))

V = 1.14 x 10^6 Volt

at infinity, V = 0

Energy expdended = q deltaV

= 8 x 10^-6 x 1.14 x 10^6

= 9.09 J
