Here is how the Fractional Charge equation looks like.

0.2083 = \frac{1E-17}{4.8E-10 \cdot 10}

0.2083 = \frac{1E-17stC*cm}{4.8E-10stC \cdot 10A}

0.2083 = \frac{1E-17}{4.8E-10 \cdot 10}

Fractional Charge Solution

Follow our step by step solution on how to calculate Fractional Charge?

FIRST Step Consider the formula

δ = \frac{μ}{e \cdot d}

Next Step Substitute values of Variables

∴

δ = \frac{1E-17stC*cm}{4.8E-10stC \cdot 10A}

Next Step Convert Units

∴

δ = \frac{3.3E-29C*m}{1.6E-19C \cdot 1E-9m}

Next Step Prepare to Evaluate

∴

δ = \frac{3.3E-29}{1.6E-19 \cdot 1E-9}

Next Step Evaluate

∴

δ = 0.208333333333333

LAST Step Rounding Answer

∴

δ = 0.2083
