Properties that define the light is a wave are

1. Speed : speed of light is 300,000 Km /s, It is most fundamenta property of light to define light is a wave

2. Reflection: Light particles or photons reflect off the particles or masses are continue to travel at the same speed.

Calculate the electric field strength required to just support an oil drop of mass

Ray Of Light [21]

Answer:

$E= 3.06 \times 10^{-17} N/C$

Explanation:

As we know that the oil drop experiment tells us the balancing the gravitational force by electrostatic force.

So ,

Electrostatic force = Gravitational force

qE=mg

Here , q is charge , E is electric field , m is mass and g is gravity.

so,

$E=\frac{mg}{q}$

Insert values from question,

$E=\frac{10^{-2}kg \times 9.8 m/s^{2}}{3.2 \times 10^{-19}C}$

or

$E= 3.06 \times 10^{-17} N/C$

This is the required value of electric field.
