the independent variables are the different
laudry detergent
the dependent variable is color of the cloth
after washing
the control variables are the amount of water
added and by washing one cloth b just water

detergent is cleaner than the cloth that is just washed by water. </span>
Answer:

Explanation:
From the question we are told that:
Charges:



Distance 
Generally the equation for Force is mathematically given by

Therefore





Answer:
The answer is 3.0 V
Explanation:
the formula of the potential due to a non-conductive sphere with a uniform charge at a point at a distance x from the center of the sphere is equal to:
V1 = (2*π*k*ρ*(3*r^2 - x^2))/3
where
ρ = volume charge density = 100 nC/m^3
x = distance from center = 0
r = radius = 10 cm = 0.1 m
Thus:
V1 = (2*π*k*ρ*3*r^2)/3
for x = 4 cm = 0.04 m, we have:
V4 = (2*π*k*ρ*(3*r^2 - (0.04^2))/3 = (2*π*k*ρ*(3*r^2 - 0.0016))/3
The difference between both equations:
V1 - V4 = (2*π*k*ρ*3*r^2)/3 - (2*π*k*ρ*(3*r^2 - 0.0016))/3
V1 - V4 = (2*π*k*ρ*0.0016)/3 = (2*π*9x10^9*100x10^-9*0.0016)/3 = 3.02 V = 3 V
