Фб = 5кВ

найти:

U, E, A

To find U, E, and A, we need to use the given values of q, Fa, and Fb.

First, let's find U, which represents the potential difference between points A and B.

U = Fa - Fb
= 15 kV - 5 kV
= 10 kV

Next, let's find E, which represents the electric field strength.

E = U / d
= 10 kV / q
= 10 kV / (0.05 l)
= 10 kV / (0.05 * 50 cm)
= 10 kV / 2.5 cm
= 4 kV/cm

Finally, let's find A, which represents the electric potential energy.

A = q * U
= 50 cm * 10 kV
= 500 cm*kV

Therefore, the values are:
U = 10 kV
E = 4 kV/cm
A = 500 cm*kV
