Hello friend...!!
1) to calculate electrostatic potential energy the formula used is,
V = Kq1q2/r^2.
V = 9x10^9 x 10^-6 x 10^-6 / 1
V = 9 x 10^-3 j.
Option 'c' us the correct answer.
2) 1 kWh = 3.6 x 10^6 J.
Option 'a'is the correct answer.
3) j = sigma (E).
option 'b' is the correct answer.
----------------------------------
Hope it is useful..!!
