Answer 2

Calculation of Electric Field Strength

To calculate the electric field strength (E) caused by a charge passing through the cross-section of a wire, we need to know the charge (Q) and the distance (r) from the wire.

The formula to calculate the electric field strength is:

E = k * (Q / r^2)

Where: - E is the electric field strength - k is the Coulomb's constant (approximately 9 x 10^9 Nm^2/C^2) - Q is the charge passing through the wire - r is the distance from the wire

In this case, the charge passing through the wire is given as 30 KiloCoulombs (30,000 Coulombs). However, the distance from the wire is not provided in the question. Therefore, it is not possible to calculate the exact value of the electric field strength without knowing the distance.

If you provide the distance (r) from the wire, I can help you calculate the electric field strength using the formula mentioned above.
