In millikan's oil-drop experiment, one looks at a small oil drop held motionless between two plates. take the voltage between the plates to be 2036 v, and the plate separation to be 2.08 cm. the oil drop (of density 0.81 g/cm3) has a diameter of 4.00 ✕ 10−6 m. find the charge on the drop, in terms of electron units.

The charge on the drop is

Explanation:

Given that,

Voltage = 2036 V

Distance d= 2.08 cm

Diameter

Density

We need to calculate the volume of the drop

Put the value into the formula

We need to calculate the mass

Using formula of density

We need to calculate the electric field

Using formula of electric field

Where, V = potential difference

d = separation of plates

Put the value into the formula

We need to calculate the charge

Using formula of charge

Where, E = electric field

m = mass

g = acceleration due to gravity

Put the value into the formula

Hence, The charge on the drop is

true tan speed = ang vel x radius

a sonic boom is a loud boom that breaks the sound barrier
