Half Potential Solution

Follow our step by step solution on how to calculate Half Potential?

FIRST Step Consider the formula

E 1/2 = 0.5 \cdot (E pa + E pc)

Next Step Substitute values of Variables

∴

E 1/2 = 0.5 \cdot (4.5 + 3.5V/m)

Next Step Prepare to Evaluate

∴

E 1/2 = 0.5 \cdot (4.5 + 3.5)

LAST Step Evaluate

∴

E 1/2 = 4
