Question

Two charges of 54 pC and - 52.3 pC are inside a cube with sides that are of 0. 3 m length. Determine the net electric flux ( in units of N- m2/C) through the surface of the cube. use ɛ0 = 8.8542x10-12 F M-1.

Select one:

a. 320

b. 0.19

c. 12

d. -0.19​

Answer 1

$∮ = \frac{q}{∊} \\ = \frac{(54 - 52.3) \times {10}^{ - 12} }{8.8542 \times {10}^{ - 12} } \\ = \frac{1.7}{8.8542 } \\ = 0.19 \\ \\ hence \: option \: \: b \: \: is \: correct. \\ \\ please \: mark \: brainliest$
