Question
Solution
Net electric flux (ΦNet) through cubic surface is, ΦNet = q/∈0 ∈0 = 8.854 × 10-12N-1C2m-2 q = Net charge contained inside the cube = 4.0μC = 4 × 10-6 Therefore, Φ = (4 × 10-6)/(8.854 × 10-12) = 4.52 × 105 Nm2C-1
Evaluate:
β729 + β49 - β16 + 1/β64
Simplify:

(1/5)(40% of 800 β 120) = ? Γ 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 β 20% of 5280) = ? Γ· 3
β157464 =?
