Millikan is doing his oil drop experiment. He has a droplet with radius 1.6 µm suspended motionless in a uniform electric field of 46 N/C. The density of the oil is 0.085 g/cm3 . Calculate for Millikan the charge on the droplet. Is quantization of charge obeyed within the precision of this experiment?

The charge on the droplet is .

Yes, quantization of charge is obeyed within experimental error.

Explanation:

Given that,

Radius = 1.6μm

Electric field = 46 N/C

Density of oil = 0.085 g/cm³

We need to calculate the charge on the droplet

Using formula of force

Put the value into the formula

We need to calculate the quantization of charge

Using formula of quantization

Put the value into the formula

Yes, quantization of charge is obeyed within experimental error.

Hence, The charge on the droplet is .

Yes, quantization of charge is obeyed within experimental error.
