Explanation / Answer

a)

here by using the gauss law

Es1 = q1 / e0

Es1 = 4.25 * 10^-9 / 8.85 * 10^-12

Es1 = 480.2 N m^2 /C

b)

by using the same formula

Es2 = -7.50 * 10^-9 / 8.85 * 10^-12

Es2 = -847.4 N m^2 /C

c)

Es3 = q1 + q2 / e0

Es3 = (4.25 -7.5 ) * 10^-9 / 8.85 * 10^-12

Es3 = -367.2 N m^2 /C

d)

Es4 = q1 + q3 / e0

Es4 = (4.25 + 2.20 )* 10^-9 / 8.85 * 10^-12

Es4 = 728.8 N m^2 /C

e)

Es5 = (q1 +q2 +q3) / e0

Es5 = (4.25 - 7.5 +2.2 ) *10^-9 / 8.85 * 10^-12

Es5 = - 118.6 N m^2 /C
