Answer 2

Calculation of Charge Power

To determine the charge power, we need to know the electric field intensity and the distance from the charge. From the given information, we know that the electric field intensity at a distance of 0.3 m from the charge is 200 V/m.

The electric field intensity (E) at a distance (r) from a point charge (Q) can be calculated using the formula:

E = k * (Q / r^2)

Where: - E is the electric field intensity - k is the Coulomb's constant (approximately 8.99 x 10^9 Nm^2/C^2) - Q is the charge - r is the distance from the charge

In this case, we have the electric field intensity (E) as 200 V/m and the distance (r) as 0.3 m. We can rearrange the formula to solve for the charge (Q):

Q = E * r^2 / k

Substituting the given values:

Q = 200 * (0.3^2) / (8.99 x 10^9)

Calculating this expression gives us the value of the charge (Q).

Please note that the specific value of the Coulomb's constant (k) is not provided in the search results. However, the standard value for the Coulomb's constant is approximately 8.99 x 10^9 Nm^2/C^2.

Unfortunately, the search results do not provide the specific value of the charge power. To calculate the charge power, we would need additional information such as the current or the time rate of change of charge.
