Flux through the 6 sides of square (i.e. cube)

? T = q i n ε 0 = 1 2 × 1 0 6 C ε 0   


Flux through a square

? = ? T 6 = 1 2 × 1 0 6 ε 0 × 6 = 2 × 1 0 6 ε 0

? = 2 2 5 . 9 8 × 1 0 3 N m 2 / C ? 2 2 6 N m 2 / C

From Guass’s Law

? E . d A = q i n 0            

E . 4 π r 2 = 0 r ( 4 π r 2 . d r ) ( α r ) 0            

E = ( α r 2 4 0 )

| τ ? | = P E s i n ? θ 4 = q × 2 a × E s i n ? 30 ?

q = 4 2 × 10 - 2 × 2 × 10 5 × 1 2

= 2 × 10 - 3 C

= 2 m C
