Polarizability Solution

Follow our step by step solution on how to calculate Polarizability?

FIRST Step Consider the formula

α = \frac{μ}{E}

Next Step Substitute values of Variables

∴

α = \frac{400C*m}{600V/m}

Next Step Prepare to Evaluate

∴

α = \frac{400}{600}

Next Step Evaluate

∴

α = 0.666666666666667C*m²/V

LAST Step Rounding Answer

∴

α = 0.6667C*m²/V
