a. Work done = 2. 0648 Joules
b. Electrical potential, V = 4. 03 × 10^10 volts
<h3>How to determine the parameters</h3>
a. Work done = force × distance
Force = density × acceleration due to gravity
Force = 5. 80 × 10
Force = 58 Newton
We have that distance = 3. 56cm = 0. 0356 m
Work done = 58 × 0. 0356
Work done = 2. 0648 Joules
b. The formula for electric potential is given thus,
Electric potential, V = 
r = 0. 0356m
k = Coulomb's constant =
kg⋅m3⋅s−4⋅A−2.
q= 1.60x10^-¹C
