Answer:
[tex]q=7.965*10^-^6C[/tex]
Explanation:
From the question we are told that
Altitude of [tex]d_1 390m[/tex]
Magnitude[tex]M_1=60.0 N/C[/tex]
Altitude of [tex]d_2=240 m[/tex]
Magnitude is [tex]M_2= 100 N/C[/tex]
Distance of cube [tex]d_c=150 m[/tex]
Generally the flux [tex]\phi[/tex] is mathematical given as
[tex]\phi=60(150)^2cos180+100(150)^2*cos0[/tex]
[tex]\phi=-9*10^5[/tex]
Generally Quantity of charge q is mathematically given as
[tex]q=\varepsilon _0 *\phi[/tex]
[tex]q=8.85*10^-^1^2 *9*10^5[/tex]
[tex]q=7.965*10^-^6C[/tex]
