| To find the value of the strength of the specified electric field in vacuum, we will use the formula: ε = E0 / E, from where we express: E0 = E * ε.

Variables and constants: E – tension in paraffin (E = 2.4 kN / C); ε is the dielectric constant of paraffin (ε = 2 … 2.3, we take ε = 2.15).

Let’s make a calculation: E0 = E * ε = 2.4 * 2.15 = 5.16 kN / Kl.

Answer: The strength of the specified electric field in vacuum is 5.16 kN / C.
