Magnetic Deflection Sensitivity Solution

Follow our step by step solution on how to calculate Magnetic Deflection Sensitivity?

FIRST Step Consider the formula

S m = (L def \cdot L crt) \cdot \sqrt{(\frac{[Charge-e]}{2 \cdot [Mass-e] \cdot V a})}

Next Step Substitute values of Variables

∴

S m = (50m \cdot 0.012mm) \cdot \sqrt{(\frac{[Charge-e]}{2 \cdot [Mass-e] \cdot 90V})}

Next Step Substitute values of Constants

∴

S m = (50m \cdot 0.012mm) \cdot \sqrt{(\frac{1.6E-19C}{2 \cdot 9.1E-31kg \cdot 90V})}

Next Step Convert Units

∴

S m = (50m \cdot 1.2E-5m) \cdot \sqrt{(\frac{1.6E-19C}{2 \cdot 9.1E-31kg \cdot 90V})}

Next Step Prepare to Evaluate

∴

S m = (50 \cdot 1.2E-5) \cdot \sqrt{(\frac{1.6E-19}{2 \cdot 9.1E-31 \cdot 90})}

Next Step Evaluate

∴

S m = 18.7553726847744m/V

LAST Step Rounding Answer

∴

S m = 18.7554m/V
